Small-Scale Question Sunday for October 19, 2025

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

I've been enjoying asking basic math questions to destroy dearly held beliefs and I would like to continue. This one requires more intuition than cold basic math though, but it's in the same ballpark.

Let's talk about housing. Housing's so fucking expensive. Especially in desirable places! YIMBYs (or maybe abundance democrats) argue we should build more housing. A lot more. But what kind of housing? Who are we trying to help?

Well. Take a town of 150k people. A one bedroom in a decent part of mine is approaching $1600 a month and inventory is also frustratingly low across the board. Before we get to my actual point lets focus on an absurd toy non-solution first. Let's build 1,000,000 Connestoga huts across town and charge $450 a month in rent. This eliminates a lot of housing pressure but anyone but the most hardcore libertarian would recoil in horror at the thought because it would mean the town would be flooded with poor single people. Per capita tax revenue would plummet while per capita demand on public services would likely increase. Traffic would explode. Parks would be overrun with trash. Police would respond to calls by lottery. This would turn the town into a nightmare.

But we don't have to get this absurd! My contention is, because of progressive taxation, public services are diminished even if you build housing that the median income family can afford!

Looking at federal income tax, the top 1% pay almost 50% in federal income tax. The top 10% pay about 75%. State and local income taxes are structured in similar progressive style. What about sales tax? More tax is paid by people who spend more, and things that are considered essential (like food and cheaper clothes) are usually exempt. Property tax? Lots with higher assessed value and luxuries are taxed at higher rates. Public service spending is carried by the affluent.

For another intuitive look at this, a family with two kids in public school will consume $3000-7500 per month(!) in state expenditure. Public education costs alone dwarf the entirety of taxes most families pay (of which only a small amount is even earmarked for education).

Not just education. The Medicare and Medicaid we all know kicks in at the federal poverty line, but the thresholds for some kind of subsidies are high enough that a family can earn as much as $85,000 in a city like NYC and still qualify for some assistance.

This means every municipality has an economic incentive to refuse newcomers that aren't making potentially 90%ile household income. This means sure, build housing, but only 90%ile housing, or become poorer.

I would like to be wrong about this! It's frightening to think of every newcomer to your town as making it per capita poorer unless they're very affluent!

One weakness in this rationale is we don't have a solid accounting of all of the transfers. E.g. if 90% of education was funded through federal and state revenues, you could imagine purpose building a town just to have a lot of schools so that people with small kids move to it and pull funds from the rest of the country and state. But I think that number is more like 60% and a lot of the "state" funds are likely a matter of appropriation and will be distributed ~right back to where they came from.

I'm kind of surprised nobody else is pointing this out! Am I hitting on some truth neither side really cares to acknowledge because it doesn't support their favorite platitudes or am I just smart enough at economics to twist myself into a gnarly retarded knot?

EDIT: oh! one argument that I've heard from a grimacing YIMBY is that he is forced to admit I am correct, but that's why we can't do this on a local level. Instead we must mandate more housing be built on a nationwide basis (e.g. a federal #NoZoneZone authoritarian order) so any one town or city would be protected from all of the poor not affluent people rushing to it at once and ruining it. This seems like a solution but I am still not convinced I am describing a true real and local deficiency.

But what kind of housing? Who are we trying to help?

Market rate; society

But we don't have to get this absurd

Why did you get this absurd then? Kind of feels like you started this off with a nice strawman to anchor on a certain tone.

"Oh you want to build housing? What if it was a shanty town?!?!?!? Anyway let's talk about this."

My contention is, because of progressive taxation, public services are diminished

I understand this to be your core thesis, although if I'm incorrect please let me know

Taxes

You are conflating progressive income taxation with municipal taxation, which is much less progressive. You also don't demonstrate that "lower per capita tax receipts" = "funding shortfall for services" you just assume that.

Federal or State income taxes being progressive does not tell us much about the marginal fiscal impact per new household in a city.

The focus on per capita tax revenue is also somewhat myopic. You could also look at tax revenue per acre/sq kilometer/sq mile and that would go up. Also the average doesn't matter, the margin does. As long as people are marginally economically net positive, you're ahead.

Property taxes account for 72% of municipal revenue. They are pretty regressive, which is why many cities have many carve outs for old people, etc.

Property taxes in my experience typically have lower mill rates in dense cities versus suburban/exurban cities. Because:

Services

The provision of almost every public service is made more efficient when provided in a more densely built area, all else equal. This is due to both physics (less meters of road/pipe/wire per person) and economies of scale.

A quick google tells me that NYC spends $36,293 per student per year which is 91% above the national average. That's $3000 a month at the highest end. Also not entirely sure why we're focusing on educational costs specifically here.

Similarly I have no idea what medicare has to do with building stuff? If Medicare is a bad system that's a federal level society problem, and not a reason to not build more homes.

Additional economic activity

You completely neglect the fact that more people = more demand for stuff and more people to work at jobs to supply that stuff = more 1%s who own the new businesses that supply the stuff so even if you want to fixate on the progressive tax brackets you'll get more of that too. Plus more 10%ers to be accountants and lawyers to support the new businesses, etc

Closing thoughts

Your argument seems to rest on the concept of "tax net takers are bad in large numbers" which is obviously true.

Your argument seems to ignore the fact that NYC, SF, Chicago, LA, London, Hong Kong, Shenzhen, Tokyo, Ruhr corridor, etc are all massive economic engines and the most productive and prosperous places in all of human civilization.

As stated above, building more results in simultaneous increases in demand/supply for everything while also bringing down marginal service costs, with the one assumption that you are in fact adding productive adults, which any non-failed civilisation should be capable of doing (given this paragraph basically summarizes 10,000 years of human economic development).

If you'd instead like to discuss how the US education system is ridiculously expensive per student (it is) or that the US healthcare system mis-allocates vast amounts of capital, much of it taxpayer's (it does) by all means do so. But don't wrap incredibly expected value positive construction in with that. You can walk and chew gum at the same time.

My contention is, because of progressive taxation, public services are diminished

Also, how did the USA's various urban areas come to dominate it's economy if this held? How did they ever work if they, according to you, should have had their tax base average down into insolvency?

But we don't have to get this absurd

Why did you get this absurd then? Kind of feels like you started this off with a nice strawman to anchor on a certain tone.

"Oh you want to build housing? What if it was a shanty town?!?!?!? Anyway let's talk about this."

Because there's two debates we can have.

  1. Is it even possible to have a line where adding people below it makes the town richer or poorer?
  2. Oh wait actually of course there is, now lets just debate over where the line is

If I don't include the absurd Connestoga huts example people get lost in believing that everyone you add to a town that's not a homeless alcoholic like Million Dollar Murray enhances it with their unique specialness. But it's pretty clear even just poor people that aren't mentally ill and are simply of modest means would also make it poorer. If you accept that, then you should be open to the idea that the line might be higher than "Connestoga Charlies" and it may in fact be people of median means.

A quick google tells me that NYC spends $36,293 per student per year which is 91% above the national average. That's $3000 a month at the highest end. Also not entirely sure why we're focusing on educational costs specifically here.

Now look up the national average. It is almost always an enormous amount of cost per household with kids that is almost certainly not paid by the median household.

The point of mentioning this is to give an example of how even modest families that aren't blatantly poor or problematic are more costly than the revenues they directly produce. You should be thinking "fuck, these hard working people who pay their taxes and aren't an obvious drain on society are actually a net drain on society" (at least if we look at direct receipts/expenses).

Your argument seems to ignore the fact that NYC, SF, Chicago, LA, London, Hong Kong, Shenzhen, Tokyo, Ruhr corridor, etc are all massive economic engines and the most productive and prosperous places in all of human civilization.

I do. But at least these places in the US were built over centuries over a variety of different economic and political climates. Lets talk about today. In case we haven't noticed, NYC isn't going out of its way to build housing that people earning $70,000/year median income can afford ("market rate" bros in shambles). If you go to any town or city's subreddit where some new development is approved you find rage that these are not anywhere close to affordable and appear to just be catering to the affluent.

I doubt the city council has economists explicitly standing up showing slide decks with a line between dead weight citizen and productive contributor near the top, but they are clearly internalizing this on some level.

You completely neglect the fact that more people = more demand for stuff and more people to work at jobs to supply that stuff = more 1%s who own the new businesses that supply the stuff so even if you want to fixate on the progressive tax brackets you'll get more of that too. Plus more 10%ers to be accountants and lawyers to support the new businesses, etc

How do we look at it? What tools do we have to measure this? This just seems like a hand-wavey way of smuggling in "Connestoga Charlies are all net contributors, too!" :hugging_face: but you were skeptical of me even bringing that type of person up at all so I assume you believe, again, there's a line somewhere. Where is it?

Great response. Thanks for following up.

But it's pretty clear even just poor people that aren't mentally ill and are simply of modest means would also make it poorer.

I think one disconnect here is that I don't entirely understand why you're so focused on the "average wealth" (so to speak) of a hypothetical city/town. I don't really care if my town's GDP (can substitute GDP with income, or net tax receipts, or whatever) per capita drops a small amount while the overall GDP goes up. The overall "line go up" benefits me greatly as the demand for the services my job provides will increase, and the supply of shit I can spend my money on will also increase. Also the amount of money I spend on housing should decrease, which means I can spend more money on funkopops or whatever. Also also ideally the provision of city services should both increase in scope and quality due to economies of scale.

That all being said yes, there is absolutely a line that if you fill up a city with impoverished people, it will go to shit. Detroit is I think a good example of this. Although the mechanism of action here was different, it had the same result of what happens when your tax base is of extremely low quality. And even then, after the exogenous shocks, it is bouncing back now I understand, kind of showing that cities are profound economic engines thanks in large part due to their scale alone. And also how lower residential and commercial rents present a much more vibrant ecosystem for capitalism to thrive.

If you accept that, then you should be open to the idea that the line might be higher than "Connestoga Charlies" and it may in fact be people of median means.

I absolutely accept that, but I am not convinced on putting it so high we're including the "median taxpayer" so to speak.

I think if the median/average adult was a net economic drain, industrial society/economy would not work. The whole of human civilization works because adults create more value than they consume, which results in the ever expanding pool of infrastructure, knowledge, and productive capacity that we've been piling on top of itself for the last 10,000 years.

You should be thinking "fuck, these hard working people who pay their taxes and aren't an obvious drain on society are actually a net drain on society" (at least if we look at direct receipts/expenses).

This may be true, given Western governments all love to run infinite deficits. This is however a top-level society problem. If our society is unsustainable, we need to fix that (it is, we do). But I don't see what that has to do with making building easier and cheaper. I would even posit that basically any fix to Western society's issues basically mandatorily has to include making building shit easier to help us un-fuck everything.

If you go to any town or city's subreddit where some new development is approved you find rage that these are not anywhere close to affordable and appear to just be catering to the affluent.

These people are stupid and don't understand how anything works. They are literally the "no take, only throw" meme.

How do we look at it? What tools do we have to measure this? This just seems like a hand-wavey way of smuggling in "Connestoga Charlies are all net contributors, too!" :hugging_face: but you were skeptical of me even bringing that type of person up at all so I assume you believe, again, there's a line somewhere. Where is it?

This is a really interesting question I don't have a great answer to.

I definitely don't believe "Connestoga Charlies are all net contributors, too". As a resident of Toronto, sympathy for the homeless is at rock-bottom, even amongst the libs I inhabit this city with.

I was skeptical because tying YIMBYism to homeless people is 1) a pretty unfair comparison (I don't want to spam low income housing, I just want the free market to work) and 2) deeply ironic given homelessness is robustly connected to the fact we don't build enough housing.

I assume the metric I'm looking for (imagining? Inventing?) is "net economic contribution" which would be some blend of tax collection vs social spending, and some type of dollar/economic gain for the additional stimulation of the economy via demand for goods/services, and the additional stimulation of the economy from using one's labour to produce more goods/services for others. Then subtract any crime/chaos/suffering that one inflicts on others and society. Connestoga Charlies are obviously deeply negative here.

Instinctively, I think the line for when this "net economic contribution" is positive is actually pretty low. Presumably somewhere around "working near full time at minimum wage job".

While the laptop class (lawyers, accountants, consultants, finance, tech, etc) capture a huge % of the economic value of society, they obviously are not the primary drivers of the massive prosperity we enjoy. They instead exist because of it.

I say this as one of the laptop class, while my skills are economically valuable, they obviously contribute very little to the production of shoes or carrots, which is what our wealth ultimately actually comes from. My job would be worthless in a society that didn't have legions of people who put shingles on rooves or whatever (as that society would be starving and falling into anarchy), even if I contribute an order of magnitude more tax dollars than they do.

Ultimately, I think the "anti-YIMBY" people (I am not even sure if you are?) need to present their solution, not just nitpick YIMBYs. Because the status-quo of western construction/the ability to build shit in response to human needs is profoundly and fundamentally broken. This is causing massive issues across society. The status quo is unstainable, full stop (unless you disagree, but that's a different argument).

So given the status quo is fucked, and if you don't like the idea of "let people build things on their land that other people want/need", what do you propose to do about it?

While the laptop class (lawyers, accountants, consultants, finance, tech, etc) capture a huge % of the economic value of society, they obviously are not the primary drivers of the massive prosperity we enjoy. They instead exist because of it.

The laptop class includes the software engineers who generate most of the marginal value which makes Americans richer than Europoors.

Connestoga

It would be nice if you were to stop consistently misspelling "Conestoga".
