Today's Thursday so it's time for #TBT: Throw-Back Thursday. ...Wait, are people still doing TBTs? Or is #TBT now a TBT thing itself? 😅\

Today's #TBT is my elementary school playground and how it changed over the years. Although I only attended that school for 3 years I remember the playground very well. ...Not just because back then, in the 3rd through 5th grades years seemed to stretch on forever— 3rd grade spanned more than 10% of my life up to that point!— but also because the school was close to home and its playground was a place I visited on weekends, during summers, and even for a few years afterward.

The earliest version of the playground had some metal climbing bars— we all called them "jungle gyms" or "monkey bars"— and a few swings on a blacktop surface. A year or two into my time as a student there the school district moved them off the blacktop into the grassy yard. I presume they figured that having kids climbing jungle gyms over blacktop pavement wasn't a great idea because of how we could get hurt when we fell. And we did fall. But back then (late 1970s) it wasn't a federal case when a kid fell off the monkey bars and hit their head on the pavement. We just got up and shook it off quickly before all our classmates joined in laughing at us.

Moving the playground equipment onto the dirt from the pavement was a good idea, but then the district backslid and put gravel down under all the equipment. I guess the problem was we were creating ruts in the dirt pretty quickly in high traffic areas, like right under the swings and at the bottom of the slide. Deep holes got filled with water when it rained, then who wants to use the slide for the next 1-2 days when there's a muddy sploosh! at the bottom. But it wasn't soft, fine-grain gravel they put down. No, it was coarse, large, sharp pieces of gravel. Back to ouchie city when we fell. And again, we did fall constantly. And again, nobody ever cared.

For many years the elementary school's playground was open. Like, there was no fence around it. There was no fence anywhere. That was cool because we neighborhood kids could play there. The school was our de facto park. There wasn't actually a public park within miles of my home— the community didn't really even have that concept— so my friends and I saying "Let's ride our bikes to the school playground" on a Saturday or during the summer was a totally normal thing.

Then they fenced in the parking lot. Okay, make it so teachers can't escape except on foot? Then they fenced in the playground. The presumptive reason was for the saaaaaafety of the chiiiiiildren. Nevermind that the statistics show(ed) crimes against children plummeting over the years. The TV showed an epidemic of dangers to children, and TV never lies.

I mostly stopped going by my old elementary school when they fenced off the playground. I mean, I still saw it a few times a month because my Boy Scout troop met there (in the multi-purpose room) Thursday evenings. But I was getting too old to want to play on a playground. Especially an elementary school playground. (Give me a playground sized for adults and I was all over it!)

At some point they replaced the gravel under the playsets with wood chips, and then replaced those with some kind of crushed rubber chips. What happened after that? For all I know they eventually removed all the swings and monkey bars because are kids even allowed outside nowadays? Do kids even want to go outside? And do anything other than play electronic games?

Metrics

I'm thinking again about metrics in the workplace. I'm specifically referring to metrics on human work. For example, "How many tasks did each person on the team complete last week?" "What's the average time for a person to do X?" "What percentage of their time is this person/this team spending on category Y?"

It's not a new thought, as I've dealt with business metrics for most of my career. I've even studied them in school as far back as the late 1980s. Plus, the idea of applying modern observation and statistics to how people do things in business dates back to the late 19th century. Metrics aren't exactly new.

But while metrics in business aren't new, often it sure does feel like everybody's just figuring them out for the first time. That's surprising to me because when I was learning about the science of process measurement in the 1980s, a lot of the pitfalls of collecting statistics on people's work were already known. They'd already been known of, and studied, for 50 years. But here we are 30+ years later and it seems 98% of everybody clamoring for metrics has no idea.

I figure the reason for that is that collecting metrics and viewing analytics reports is trivially easy now. So much of our work is managed through computer software. With the computer already in the loop, metrics fall out practically for free. Anyone can suddenly get reams of data and colorful charts. But what do those charts mean? What are the limits of usefulness, accuracy, and predictive power behind the colorful lines, boxes, and pie wedges? When metrics were kind of a specialty, you'd have a person educated in the field to set up, collect, and interpret the data. You'd have an expert with the numbers. Now any noob can get numbers, which means any noob can suddenly feel confident their novice opinion is correct because they've got data.

Our niece, A., graduated high school. The ceremony was last night.

My sister and brother-in-law celebrate their daughter's high school graduation (Jun 2024)

These are her parents, my sister and brother-in-law, with her after the commencement. (Yes, the background there is the folded up tables of the high school lunch room. 😅)

Some students' families went all-out to celebrate their graduation. Some had huge, loud cheering sections. I saw at least two groups with personalized t-shirts, sporting a picture of the graduate on the front and emblazoned with text specifying their relationship-- "My son/brother/grandson has graduated!"

I teased my family that we were going to paint their car up like this:

"My Kid Done Gradiated!" - a possibly staged but humorous meme going around this graduation season (Jun 2024)

Or maybe paint our car, "Are Neice done Gradiated!" 🤣

BTW, last night two of are neices done gradiated! A.'s cousin, B., graduated from high school in Virginia. Family couldn't be in two places 1,000 miles apart on the same day, so Hawk and I joined here, while my mom and youngest sister celebrated with B. and her parents.

And yes, A. has college plans all lined up. In September she's starting at Savannah College of Art & Design.

After 15-year-old Ethan Crumbley brought a gun to school and murdered 4 classmates and injured 6 other students and 1 teacher at his Michigan high school in November, 2021 prosecutors charged not only him but his parents. The theory of the case against the parents was that they ignored abundant signs their minor child was making violent threats, bought him a gun, and failed to take steps to secure the gun. The parents were tried separately. Last month Jennifer Crumbley, the shooter's mother, was found guilty on 4 counts of involuntary manslaughter (ABC News article, 6 Feb 2024). Today James Crumbley, the shooter's father, was convicted on 4 counts of involuntary manslaughter (ABC News article, 14 Mar 2024).

One of the telling pieces of evidence in the parents' trials was a picture a teacher snapped with her cellphone hours before the shooting. The shooter allegedly drew this in math class. The teacher, alarmed, notified school administrators.

Previously I described this picture in words. This time I'm going to share a scan of it I found online (widely reported now as it was evidence in criminal trials) because it's so freaking obvious as a warning sign:

A teacher snapped a picture of a student drawing on a worksheet the day of a school shooting in November, 2021

The drawings show a handgun, a bullet, and a person apparently injured with gunshot wounds and a large pool of blood. Written next to these drawings are "Blood everywhere" and "The thoughts wont stop Help me". Elsewhere on the page were and "My life is useless" and "The world is dead".

The school principal called the boy's parents to the school and showed them the drawing. By then the boy had crossed out parts of the his doodling and added some cheery phrases. But the alarming parts were still visible. The parents denied there was anything wrong with the drawing and flatly refused, when asked, to take their son out of school for the rest of the day. Ethan Crumbley went on to shoot 11 people, killing 4 of them, later that day with a handgun he already had in his school bag.

Among the parents' defenses at their trial was that they didn't know their son was troubled. They hadn't seen any signs. WTF?! How much more obvious of a sign did they need?!?!

BTW, this wasn't the only sign. There were other incidents at school, too, where teachers and administrators reported concerns to the parents. The parents dismissed all of those, too. And in other evidence it was shown they at least knew he was feeling bad. Their solution? They bought him a gun and gave it to him as an early Christmas gift as a pick-me-up. It was the gun he used a day later to shoot 11 people, killing 4.

Tomorrow, March 5, is the 2024 primary election in California. That means today I filled out my ballot and sealed it up to drop off at the ballot box tomorrow. Yes, California is one of those voting rights states where everyone can get a mail-in ballot, no questions asked. Mail-in ballots are much easier for people whose job and or family situations make it prohibitive to carve out time on election day to go to a polling station, wait in line, and fill out a ballot provided only then and there.

Here's a run down of the main things on the ballot this time.

President: I'll assume if you can read this and are eligible to vote in the US, you know what the choices are here.

US Senator: It's a race to replace Diane Feinstein, who died several months ago. Actually it's two races, making it more confusing. One race is to fill her seat for the remainder of her current term, which ends 3 January 2025. The other race is to be US Senator from California for a full, 6 year term.

Both of these senate races follow California's "top two" primary rule, which is also affectionately known as a "jungle primary". Numerous candidates run in the primary, and the top two vote-getters advance to the general election. This narrowing of the field is done without regard to political party, so it's possible the general election could feature two Democrats running against each other and no Republican.

There are three credible Democrats in this race. All three are sitting members of Congress: Adam Schiff, Barbara Lee, and Katie Porter. The leading Republican is past baseball star Steve Garvey. Schiff leads among all the candidates and has spent a lot of his considerable campaign money telling people Garvey is a conservative. Poll watchers agree this seems to be a play by Schiff to shape the results of the "top two" primary by boosting Garvey to be the #2 finisher. If that happens Schiff would presumably coast to a win in the general election, given the overwhelming registration advantage Democrats have in California, versus having to fight it out against a fellow Democrat.

US Congress: Again, a "top two" primary race, though with only a handful of candidates rather than the dozens in the senate race. Here our incumbent, Rep. Ro Khanna, has been doing a pretty good job, so I gave him my vote again.

State Assembly: My district's incumbent Assembly member, Evan Low, is termed out this year and is seeking higher office. He's running for US Congress (though not in my district). I usually don't pay much attention to State Assembly, but this year I went to a meet-and-greet with one of the candidates, Patrick Ahrens. I went into that backyard rally skeptical and left shaking his hand and telling him he'd earned my vote. This is a race where I politely disagree with my friend [personal profile] mithriltabby who posted his usual well-researched recommendations a few weeks ago. Edit: I don't think the opponent of Ahrens's he chose is poor but I do consider Ahrens a stronger candidate than he gave him credit for. I found Ahrens to be intelligent, thoughtful, and skilled at bringing together political leaders across different levels of government to solve challenging problems, like housing for the homeless, that are often dismissed with finger-pointing about who else needs to be involved. Ahrens has a record of not just identifying who else needs to participate in the solution but actually getting them to help.

Proposition 1: There's just one statewide proposition this election. That's a good thing, because such significant measures as statewide initiatives shouldn't be passed or rejected in elections with such low turnout as primaries. In fact, the state passed a law (via ballot proposition 😂) to force most props to the general election. Anyway, this prop is clumsily named "AUTHORIZES $6.38 BILLION IN BONDS TO BUILD MENTAL HEALTH TREATMENT FACILITIES FOR THOSE WITH MENTAL HEALTH AND SUBSTANCE USE CHALLENGES; PROVIDES HOUSING FOR THE HOMELESS." Per the information in the state voter guide it changes up how money under an existing law is allocated, shifting more of it to mental health care, housing, and drug addiction treatment. It also includes a new bond to help fund these. The measure isn't perfect, as my friend mithriltabby points out, but unlike him I support it anyway. I side with The League of Pissed Off Voters in San Francisco who also explain that Prop. 1 is imperfect but voting "Yes" is far better than voting "No" for anyone who cares about the dual crisis of drug addiction and homelessness. I drive past growing tent encampments 1/2 mile from my house several days a week. I'd very much like to see them gone— and not by police rousting the homeless and simply forcing them to move elsewhere, but by us providing a compassionate, superior alternative.

Measure C: This one's a local school district bond proposal. It authorizes up to $214 million in bonds to improve local schools, paid for by a surcharge on property taxes. That may sound like a lot of money, but it's only at most $15 per $100,000 of assessed property value. For roughly a hundred bucks a year I'll invest more in local schools. I don't use the schools myself, nor do I have any schoolkids, but if our schools go up even a point on statewide scores it'll add thousands to the value of my house. So even if I didn't think educating the next generation is the right thing to do (it is the right thing to do) there's still a selfish argument to be made for it.

Recently I saw a thread online about school field trip fails. On the list are failures of planning, organizers not appreciating what students actually want, crises created by student misbehavior, and even just a few plain-old accidents. That reminded me of a field trip I found particularly disappointing.

When I was in second grade, my class visited the local fire station. Fire stations are pretty cool, right? There are those big trucks to look at (they're extra big when you're little second graders!), all the interesting gear firemen have, and of course, the firemen (and firewomen— though there weren't any back then) themselves. Except when we rolled up to the firehouse in our school buses the trucks and teams had just rolled out to respond to an emergency call. The station was empty.

I remember the several dozen of us 2nd graders wandering around the empty station. The garage built for fire trucks sure seemed huge without the fire trucks in them. And all the fancy gear? Well, most of that was gone, too. There was, like, one pair of boots left over. Hey, kids, look! A pair of boots!

Maybe saddest of all was that we didn't even try waiting to see if we could tour the station after the crew returned. The teachers packed us back up into the buses to return to school after a few minutes of aimless wandering. Maybe they only booked an hour for the trip including the travel time.

Moral of the story: Don't plan a field trip to the fire station when there's also a fire scheduled!

North Carolina Travelog #15
Back at the hotel - Thu, 21 Sep 2023. 10pm

Today has been an amazing day. We went on several hikes and visited a whopping 10 waterfalls... all within a 30-45 minute driving radius of our hotel. I didn't even realize it was 10— I kind of lost count after 5 or 6— until we got back to our hotel room this evening and I sorted through my pictures.

As deliriously happy as we were throughout the day we also had moments of self criticism. You know, that feeling you have when you're doing something that is amazing and you pause to reflect, "Okay, this is amazing.... Why didn't I do it sooner?"

In our case "sooner" could have been twenty-some years ago when we lived in North Carolina. We lived here. Well, not here-here in the Blue Ridge Mountains. We lived a few hours away in Chapel Hill, NC. I was doing my grad work there, and Hawk stayed with me two summers between finishing her undergrad in another city. We could have made weekend trips out here.

The US Supreme Court has ended race-based affirmative action in universities. I know, unless you've been living in a cave that's not exactly news anymore. The Supremes handed down their somewhat predictably 6-3 decision (with its super-majority of conservative and ultra-conservative justices) just over two weeks ago, on Thursday, June 29. Example coverage: NPR News article, 29 Jun 2023.

Most things I could say about this decision have probably already been said elsewhere— especially because I am late to the party by about two weeks. But one thing I heard in the hours following the decision I've not heard or seen repeated anywhere, so I'll share it here.

A college admissions officer at a highly selective liberal arts university was being interviewed (quote slightly paraphrased):

"We've accepted as an assumption in our national discussion on the issue that college admissions is an objective assessment of a student's educational qualifications, and that anything else is discrimination."

The admissions officer went on to explain that college admissions is, in her view, really about what kind of community the school wishes to build. But it's the statement highlighted above that has stuck with me— because of the absurdity it contains.

How can there be an objective assessment of educational qualifications? It's a myth that there can be such a thing. Numbers like SAT scores, ACT scores, and even AP test scores have been shown for years to have limited correlation— reasonable correlation, just not strong correlation— with academic achievement post-high school. Heck, that was established long enough ago that I read the studies in textbooks published in the 1980s when I was in college in the 1990s. And just about everything else about an admissions decision is less numerical, less standardized than that, and therefore requires way more subjective evaluation.

Earlier today I began sharing my opinions about the statewide propositions on the ballot in California. See Ballot Propositions - Nov 2022 - part 1. Here in part 2 I address the latter four props on this November's ballot.

Prop 28: Lock in Funding for K-12 Arts and Music: Gentle No.

A few days ago I wrote blog entry The Problems with Propositions. Prop 28 is exactly the sort of measure I had in mind when I explained the trouble with props that lock in spending requirements. The bill would ensure a certain baseline amount of funding for K-12 arts and music education. To be sure, supporting such education programs is a worthy goal. And because of that it may well pass. I mean, who could be against teaching art and music to kids? But here's the thing: a vote against this initiative is not a vote against art. It's a vote against tying the hands of state legislators in the budgeting process.

This year California's budget spends nearly $100,000,000 on K-12 education, an average of $17,000 per student. For context: yes, that's a lot. And it's a lot partly because the state has enjoyed strong tax revenues for several years. But strong revenues are not a given. During an economic slowdown— of the sort that most economists, business leaders, and even ordinary citizens are predicting will happen next year if not sooner— California's tax revenues fall. Legislators then face tough choices in where to allocate funds. Each voter-passed initiative that locks in funding for one item or another makes the decisions about where to spend the remaining money more dire. Lock-ins for art and music may mean that school programs for language suffer... or perhaps that programs for supporting the elderly or combating climate change get short shrift.

Again, I recognize that supporting art and music education is a sympathetic choice. The only problem I have with this bill is that it's a funding lock-in. That's why I'm calling my position a Gentle No on 28.

Prop 29: Dialysis Clinic Regulation: No.

Patients who need kidney dialysis face dire straits. Shouldn't the industry that keeps them alive be better regulated? Don't be fooled; that's not what this is about.

This initiative matches at least 2 of the 5 proposition problems I described the other day. First, regulation in an industry that is a matter of life-or-death for certain individuals is a deeply detailed bit of policy that  shouldn't be left to ordinary citizens to enact on strict up-or-down votes.

Second— and more importantly— this is a special-interest, self-dealing initiative in disguise. Follow the money to see who is bankrolling this and understand why. Funding comes almost entirely from the Service Employees International Union-United Healthcare Workers West union, which has been fighting with the two major providers of kidney dialysis over workers' contracts for years. This is now the second time in recent years the SEIU has gone to the ballot box in an attempt to gain extra leverage in negotiations. I support unions fighting for fair pay, benefits, and working conditions. I do not support them misleading voters at the ballot box to win what they cannot win in equal party negotiations. Vote No on 29.

Prop 30: Tax the Rich to Fight Wildfires and Climate Change: No.

Ah, Prop 30, another measure with a worthy-seeming set of goals. Wildfires are already a very destructive phenomenon in California, costing billions annually, destroying homes and habitat, and often causing deaths. Who could be opposed to reducing the risk of wildfires? Especially since as bad as they are now they're expected to get worse as a result of climate change.... Which this measure nominally also fights. Who but climate deniers doesn't want to fight climate change? And who better to soak with the bill for all of this than California's highest income citizens, those making over $2 million per year?

Alas, Prop 30 is another case of a moneyed special interest looking to do itself a favor at taxpayer expense while using a noble goal as a disguise. Follow the money and you'll see: a) the measure's main sponsor is ride-share company Lyft, and b) the measure's main expenditure is subsidizing purchase of electric cars and the construction and operation of recharging stations. How does (b) relate to (a)? California recently passed a law requiring all new cars sold be electric by 2035. Lyft depends on a huge fleet of vehicles... which it wants taxpayers to subsidize its contractor-employees buying & refueling.

Look, I'm all in favor of vehicle electrification. And I don't like wildfires or climate change. But this tax-the-rich-to-subsidize-a-huge-company measure is the wrong way to further either of those goals. It's a flawed and self-dealing initiative. Vote No on 30.

Prop 31: Uphold Law Banning Flavored Tobacco: Yes.

Prop 31 is a referendum... Instead of being an initiative proposing to create a new law, it is an initiative allowing citizens to veto an existing law. Many voters feel confused and irritated by so many props each year that they take a stance of "I'm just going to vote No on everything!" This is one of the cases where that mindset is misplaced. With a referendum a Yes vote upholds an existing law and a No vote removes it.

What's the law at stake here? 2020 the California legislature approved, and the governor signed into law, a bill banning the sale of certain flavored tobacco products. Cigarette smoking is a major public health hazard generally speaking, and flavored tobacco products have repeatedly been shown to appeal to underage smokers, hooking kids on a destructive, lifetime habit. It's important to attempt funded by the tobacco industry (again, follow the money) to veto our laws— and to do that voters must vote YES on 31.

President Biden announced student loan debt relief yesterday. Under this program the Department of Education will forgive up to $10,000 of federal student loans for borrowers under certain income limits. Borrowers who also received Pell Grants (a subsidy for low-income families) are eligible for up to $20,000 of forgiveness.

Biden's plan has supporters and detractors. The detractors are all over the political spectrum. From the left, people are saying it's not enough. "I'm 65 and have $300,000 of loans!" read multiple news headlines. From the right it's being called everything from unfair, to inflationary, to theft— and that's just in the mainstream media. I can only imagine the unhinged claims echoing around the fever swamps of conservative media.

The new program is not directly relevant to me; I paid off my student loans years ago. But there's an interesting what-if. What if a program like this were available years ago? What if I had just graduated recently and still had loans to pay off?

— I was fortunate to graduate with a relatively small loan balance. I qualified for academic scholarships that, together, covered at least two-thirds of my costs. Work during the year and during the summers covered at lot of what was left. I graduated after 4 years with loans of just $6,000. That was lower than the debt a lot of people graduating around the same time owed.

— Of course, $6k then is not $6k today. Applying a simple inflation adjustment doubles it to $12,000. College costs have risen much faster than the rate of inflation, though. Instead of merely 2x due to inflation it could be 4x if scaled proportionately to how the full cost of the private college (Cornell University) I attended has grown since then. So, maybe $24,000 if I graduated earlier this year.

— Even my hypothetical $24,000 loan is a light burden. Figures from the Education Data Initiative reported in a recent USA Today article indicate that the average federal student loan balance today $37,667. I think that represents the balance after people have already paid whatever they've paid. The average upon graduation would be higher. And the average upon graduation from an expensive private school would likely be a lot higher, too.

But let's go with the figure of $24k. That's like a new car loan. I'd be graduating from college and already owe as much as financing a new car. (And not a fancy new car, BTW. We're talking Toyota Corolla money here.) I'd welcome debt relief of $10k. It wouldn't pay off loans of $24k but it sure would make a big dent in them. Even if my loan balance were $40k, knocking out a quarter of that would be nothing to sneeze at. Edit: $10k is $100-200/month depending on term. Not a huge amount, but enough to make a difference for anyone struggling to pay for basics each month. I'd sure appreciate the government giving me a hand-up as I started my career.

The Supreme Court Monday issued its ruling in Kennedy v. Bremerton School District. The case concerned a high school football coach, Joseph Kennedy, who was leading students in prayer at midfield after football games. Lower courts upheld the school district's decision to put Kennedy on paid administrative lead for illegal promotion of religious activities at an official school event, a violation of the First Amendment's establishment clause. The Supremes overturned those decisions, though, ruling that it was a legitimate, private expression of personal faith protected by the First Amendment.

One of the issues on which this case (or cases like it) turns is coercion. Yes, the prayer is nominally voluntary in that students are invited to join; but when it's a school authority figure who's leading it, there is enormous pressure on students to go along. The coach is the boss of who gets to play, in which position, and for how long. He's also a role model for the students. A student who objects to the group prayer— perhaps because he practices a different faith or perhaps is not religious— may find himself denied opportunities to play and ostracized by fellow students who support the coach.

Some cases about prayer in school have so-called gray areas. This case is not one of them. What happened here was, or should have been, black-and-white.

So, how did the Supremes decide 6-3 to ignore the obvious conclusion in this case? Well, they simply ignored the facts of the case. They. Ignored. Facts.

To underscore this point, Justice Sotomayor included pictures in her dissent. Pictures of large, loud scrums of people— not just team members but players on the opposing team and fans from the stands including local politicians— flocking onto the field to join the coach's prayers. Justice Gorsuch's majority opinion characterizing the prayers as "private" and "quiet" is simply dishonest.

This past weekend nationwide rallies were held by March For Our Lives, a student-led organization calling for action to reduce gun violence. The rallies reminded me of a question I've asked myself a number of times recently. If I were a grade school/high school student, or a parent of a student, what would I do? Besides attend a rally, I mean. Specifically, would I refuse to attend school or send my kids to school until meaningful steps to protect students are taken?

"Protest by refusing to go to school," is an easy thing to say. And indeed, various protest organizers have suggested it. Often it's a one-day or half-day thing; "Skip school this Friday to protest gun violence." But in some corners it's "Refuse to go at all" until political leaders meaningfully address the problem.

The problem with skipping school is that it's not a solution. It does nothing to raise the pressure on the intransigent political leaders who've thwarted meaningful change for 40 years. The mounting death toll of students mowed down in their classrooms by angry people with paramilitary weapons hasn't appealed to their better angels; so all that's left now for protest is to make them feel the pain of the situation they've created. Students skipping school does not do that. The people most hurt by that are the students themselves. They lose educational opportunities, they may be disqualified for a high school diploma, their prospects for college are jeopardized. I can only imagine how risky it would've been for me to tell the highly selective colleges I was applying to as a teenager, "Well, I didn't actually get a H.S. diploma because I was staying home to protest lack of public safety." Likewise if I were the parent of a high school student I don't think I could in good faith support them choosing to stay home.
canyonwalker: Mr. Moneybags enjoys his wealth (money)
Today I read about an interesting tweet that went viral last week about MBA students overestimating what the average US worker earns:


Nina Strohminger is a professor at Wharton, the MBA program of the University of Pennsylvania. Wharton is currently rated as the #2 business school in the US.

"Lies, Damn Lies, and Statistics"

Most of the viral discussion about this tweet has been about how out of touch the MBA students are and why that's actually common— not just for people who tend to come from affluent families but everyone. My immediate thoughts were along those lines, too. But then I realized that before we even get to debating why this is, we need to look at the problems with the statistics. Professor Strohminger has actually done a poor job here. Five Things:

  1. Okay, so one-quarter of the students think the number is $100,000+. What about the other 75%? What threshold fits the lowest one-quarter of answers? What was the average?
  2. How many students were surveyed? Small sample sizes yield meaningless results.
  3. What efforts were taken to ensure the students participating are representative of the class? (Since so much of the viral discussion is about characterizing Wharton students, or MBA students in general, or academic elites in general.) And were they taking it seriously? The person who answered $800,000 was likely ridiculing the question. How many others might have done the same?
  4. Did you specify median or mean? These figures are very different.
  5. The "correct" answer is also different depending on not just median vs. mean but also full-time vs. part-time work. Many policy experts would argue a better metric is median household income.


Am I Smarter than a Wharton Student?

FWIW my quick answer was $65,000. That's not correct for the exact question the professor asked. Though even her answer seems incorrect. The Social Security Administration reports that last year the mean US wage was $53,383 and the median was $34,612.

My $65k answer comes from thinking about median household income— a better measure than individual income for purposes of many economic policy discussions. I recall looking up the $65k figure when I was writing about US socioeconomics a few years ago, so that's why it was my immediate answer here. On that metric I was actually very close. According to the US Census (2020) it was $67,521 in 2020. It was higher in 2019, at $69,560. Likely it was $65,000 a few years ago.

What do you remember most from school, particularly the earlier years? Here's an infographic I made about the lesson we were taught most frequently:

Stop, Drop, and Roll: We practiced this at least once a week!

Seriously, we drilled on this at least once a week, but they never taught us how to balance a debit account. Guess which skill I've used exactly never and which I've used multiple times a week for decades.

Though they did teach us, once, to buy the cheapest stereo or end up homeless. 🙄
