This analysis, for whatever it's worth, is wrestling with a straw man. Klein and Thompson never claim that permitting reform is the only lever available. The housing strategy Abundance documents is that of the YIMBY movement, and YIMBYs are all-of-the-above advocates. If you can get subsidized housing built, you get it built. Meanwhile, you fix exclusionary zoning and clear a path for the market (which produced virtually all the homes we live in) to function as well.
I'm hugely in favour of adding non-market housing anywhere it can be added, but the author declaring it a different fix to the housing crisis from zoning is naive at best. Non-market housing is subject to the exact same complex local regulations as market housing, plus all the complexity of government projects, a patchwork of subsidies, grants, and loans to get funding, and even more intense public scrutiny. Trying to get social housing done is playing an exceptionally hard game on nightmare mode.
The single lever he points out is itself a ton of local, regional, and federal regulations and laws that all need modernizing or abolishing, which is far from a simple, single lever at all.

Worth mentioning here that appeals to social housing have over the last 20 years been absolutely classic NIMBY arguments. People raise it because they know significant amounts of social housing won't get built, but if you fix the gating factors for the market, it will.
But this is also a factional concern; for reasons I don't understand, the Democratic left polarized hard against "abundance" (and thus YIMBYism). So these kinds of arguments now code as "centrist".
Nathan J. Robinson actually said the quiet part out loud a couple years ago, when he wrote in Current Affairs (a relatively high-profile American leftist periodical) a long defense of suburban NIMBYism.

To be slightly glib: the left has no greater enemy than someone who agrees with them 95% of the time.

I think a lot of these activists were originally fighting gentrification. Then, over time, the gentrifiers won anyway, and now most housing in hcol areas is occupied by wealthy professionals. But the activists never updated their politics (people have a hard time admitting—or, sometimes, realizing—that they lost), and now they advocate policies that shut out the people they originally set out to protect.

The old school granola hippie left (anti nuclear types who love coal and gas) seem to think that “making things people want and selling them for money” is fine until it’s homes, when it suddenly becomes evil.
There’s also a failure to see second or third order effects. Yes, up zoning means that new homes will be expensive at first, but over time prices fall as demand and supply reach equilibrium. Similarly rent control is a feel good policy to screw the young and newcomers in favour of incumbent renters.

Of course one of the reasons social housing won't get built is the faircloth limit from 20 years ago.
That's like 4-5 principal components back from the first principal component, which is that the places that need housing market vitality the most could not reasonably afford to acquire the housing to support it. The best school systems in Chicagoland are in the inner-ring suburbs, locked up for SFZ residents. Even if their municipal governments wanted to go all-out to fix that, they couldn't conceivably acquire the land and arrange the development.
Worth adding that "public housing" isn't the only or even the most common form of subsidized housing. There's no Faircloth limit at all to public-private subsidized housing with AMI-calibrated eligibility and rent, and that's a much more common form of subsidized housing than a "housing project". But it can't get built in meaningful numbers either, because it's simply too expensive.

Also, if municipal governments "fixed that" by making it possible for more housing to be built and more people to move into neighborhoods served by those currently-good school districts, the odds are good that the influx of new students would make the school district worse. And the people currently living in single-family zoned residences know this - one motivation for NIMBYism is that it helps maintain the high quality of the local school district where your kids currently attend school.
I'm personally in favor of abolishing public school districts, precisely so that the location of a house is no longer a major deciding factor in where any children in that household attend school. This reduces the incentive for people who live in a house in a good public school district to resist building any more houses in that school district, lest the inhabitants of that house make the school district less good.

School districts per se isn’t the problem so long as you have enrolment catchments. Australia doesn’t have school districts for their public schools but there are definitely more and less attractive state schools and people definitely pay more to live in the catchment zones of good schools. https://www.reddit.com/r/melbourne/comments/12bgjnt/victoria...

Setting aside the inevitable transportation issues this is an excellent policy that I would love to see implemented, but I think too many suburbs built their identity around “having the (property tax base necessary to create the) good school district.”

Oh, it's a far worse problem than having the property tax base to create the district, but avoiding the students that would need extra support, and might disrupt the classroom because they aren't getting it. Those students are incredibly expensive to handle mainly via the school district alone. The amount of money to provide sufficient support without parental involvement is beyond what even the wealthiest districts can afford. The shortcut to avoid said students isn't to have immense funding then, but to make sure parents that aren't rather wealthy don't even get into live in the district a all.
That's the real dirty problem of the suburb + school district marriage: You turn parents just thinking of the school district of their children into raging NIMBYs that end up wanting just rich people that speak perfect english nearby.

I’m from a country with such a system. You end up with your children all going to different schools, attending parent teacher meetings all over the country and spending lots of time dropping of the children at multiple schools.
Seems pretty straightforward to implement a rule saying siblings go to the same district by default. I’m sure there are a bunch of edge cases, but the assignment process doesn’t have to be totally random.
For centuries, Roman Catholics belonged to territorial parishes. That is, wherever they lived determined which parish they attended, and they also had obligations to support the material needs of this home parish, and their home pastor had a significant influence on whether these folks could marry or pursue a vocation to the priesthood or religious life. Of course, any family with children would send them to the parochial school where they belonged (there were often regulations that prevented the kids from going anywhere else.)
However, the popularity of cars, highways, and general mobility all over the place, has caused many bishops, particularly in the United States, to sort of supersede these territorial rules. Now in my diocese, a Catholic can go attend any parish they want to, and register in that parish, and for all legal purposes they are an official member of that parish, as if they lived within the territory. There have always been parishes like this, called "personal parishes" but they were often defined by certain ethnolinguistic qualities, like everyone from Poland, or Vietnam or something.
So now this leads to some crazy situations. For example, my friend was received into the Church from Lutheranism, and when this happened, he lived in a particular place. But he's moved away--far, far away--twice, and yet he still "commutes" to that parish where he became attached and still loves, and still has commitments and responsibilities there, which he upholds.
There are also people who, for liturgical or doctrinal reasons, will drive for hours on Sundays just to reach a church that agrees with their personal beliefs and preferences.
I am not sure this is sustainable or realistic. If eventually you have Catholics driving all over creation, literally, to get to their preferred parish, then some parishes are going to languish, if they cannot attract or retain people who are willing to volunteer there, support their material needs, and send their kids to the parochial school. That means schools are going to close. There are also independent schools popping up, that are not parochial, but approved, and Catholics send their kids there. Failing that, they get homeschooled.
I think this extreme mobility thing is absurd. I can't keep up, obviously, having no vehicle. It was actually easier for me to commute to a parish I didn't "territorially" belong to because of the way public transit works, but eventually I decided to stop commuting, and be honest, and live up to responsibilities of the parish where I belong, territorially, even if that is now a de jure thing of the past.

If we’re thinking about the same essay it’s a criticism of capitalist YIMBYs who are only interested in building McMansions and the like. It is both anti-NIMBY and anti-some-YIMBYs, which seems reasonable to me.
EDIT: Historically, some YIMBYs have not opposed—I guess we’ll call it instead—unaffordable housing. So-called “capitalist” or “libertarian” YIMBYs in particular. Robinson’s article describes this. Leftists are skeptical of “all housing construction makes housing more affordable” arguments, and there’s evidence presented in the article to that effect.

Capitalist YIMBYs oppose McMansions. They're like the central thing we oppose. The whole point of the movement is replacing large-lot-coverage single-family-homes with multifamily. The whole point of YIMBYism is multifamily housing.
Understand: there isn't regulation against large single family homes. You can build a McMansion anywhere you want already. Your analysis makes no sense: nobody needs to organize anything to allow McMansions; they're the regulatory default. But suburban progressives genuinely believe stuff like this! It's a real problem.

More like a straw army.
Austin is surrounded by empty flat land. San Francisco is surrounded by water and was built out many decades ago.
London suffers from being the main city in Britain. The UK is overcentralized. Most of the money and power are in London. Some countries are centralized like that, with all the good stuff around the national capital. France, Japan, and Russia are; the US, Canada, and China are not. (China, maybe; too much is near Beijing, but there are lots of other big cities.)

SF still has lots of low density that could be demolished in favour of higher density housing though.
Yes, plus, all these meta-studies always seemed to ignore the reasons for the demand shock.
"It's not the permits, it's the demand shock" (the last image in the blog post). The "demand shock", was the economy growing...quickly. And that statement is left hanging in the air like we're supposed to do something about it.
The economic growth is a good thing, we should have a housing system that reacts to it like surge pricing but instead we get a lot of hand-wringing then rezoning 5-10 years too late, so instead of temporary surge pricing, we get permanent ultra-heavy-high-surge pricing.

The housing claims in the book are basically unfalsifiable as written. It might be a straw man, but at least it’s a concrete result.

People can write what they like on their blog, but this article seems to be missing key details - we don't find out what the model is or the coefficients he's using and the model apparently immediately produces unrealistic results. Hopefully it is made clear in the book, but unless someone has read Abundance it is hard to follow.
If the model is just a rough rule of thumb then spot checking 4 cities in completely different legal frameworks, cultures and economic situations doesn't give us a lot of data. Economies are very complicated and any effect can be overruled by something unrelated but more impactful happening.

This is interesting analysis, but I don't think it necessarily counteracts what the book is saying. To build state-affiliated housing also involved "clearing the pipes" as the article put it.
Additionally, the Vienna housing that this article touched on is a way deeper rabbit hole that is absolutely worth looking into. They have a completely different housing paradigm than pretty much anywhere else in the world.

(For the uninitiated, the government [and sponsored co-ops] owns almost half the housing in Vienna, and eligibility for social housing, which is seen as desirable, extends deep into the middle class.)
There's no free lunch. Housing costs are effectively carried by immigrants and transplants: https://www.aei.org/wp-content/uploads/2023/09/Setting-the-r...
In general, the Vienna model is very difficult to copy without being in extreme conditions: https://www.threads.com/@__smiz/post/Cxpz28CIkT6

Many people also don't know that Vienna was isolated and divided for nearly 50 years during the cold war. A significant amount of the available housing is due to Vienna having a bad economy for almost a century.
The reason "many people dont know" about that is that it didnt happen.
You just made it up.

Berlin was divided.
Like Berlin, Vienna had occupation zones, but there was never a wall between them.

Huh? I thought that Vienna's partition period following WWII lasted more like ten years than sixty.

Vienna was under occupation for 10 years but was never partitioned. There was mostly free movement of people and goods between the zones.
Is this similar to Singapore where much of the housing stock is government housing?
I am also reminded of (former-?) rival Hong Kong, where the government either runs or subsidizes at least half the housing. (This in turn relies on other idiosyncrasies, like the government owning all the land, a massive sovereign-wealth fund, etc.)
I get the impression the author may not have made it to the end of the book where a lot of these positions are better addressed.
I can take out my copy and explain better later today, if it’s interesting.

Hint: if you see "Austin" bandied around as a good example, then you know shit about housing.
Austin rent decreases happened because of its stagnant population, not because of new construction. It's barely growing _at_ _best_, and I predict that it's actually _shrinking_.
You can play around with the ACS dataset yourself: https://data.census.gov/table/ACSDP1Y2024.DP05
The 1-year estimate for 2024 is 993771, barely up from 979263 for 2019 (there is no 1-year estimate for 2020).

I like how they're using real numbers and theorizing around that. An interesting next step would to dive in deeper, to see up close where it's bottlenecking.
Progressives and Democratic Socialists like to pretend that the government can pass a law which would allow it to build lots of social housing/provide health care for everyone/build a lot of green energy/etc and it would just go and do that easy peasy. But building housing and infrastructure is not something you can just snap your fingers and it happens. It’s not something you can just throw tons of money at and pops up over night. Governments have to spend years and decades building systems and institutional knowledge around these things. The reason people can make a lot of money building houses is that it’s really hard and requires a lot of specialized and localized knowledge to figure it out.
This is a lot of what Abundance is actually about. Part of it is saying “yeah, let’s take the time and build state capacity to be able to do some of these things”. Vienna is able to build social housing because it’s been doing it consistently for decades and has all the right systems in place to do it. It’s not a libertarian book that just says “get rid of the rules and let capitalism sort everything out”. It’s about figuring out the right set of rules and incentives that allow governments to sustainably build things, or else facilitate the market to build them.

It’s always fascinating to see when “this is hard and expensive to do, so we shouldn’t even try” is considered a compelling argument (housing, health care) vs. when it isn’t (defense, policing, the modern panopticon).

That's true if we're talking residential structures using load bearing masonry in America. Modern timber-framed houses? Nope.
> It’s not something you can just throw tons of money at and pops up over night.
If this is true for your locale, the reasoning always boils down to the slow pace of bureaucracy. Needing this permit cleared, then this one, need this plan signed off on, need this approved, etc. Of course, you can absolutely expedite the process by throwing money at the problem. The wealthy do that in LA all the time, to shorten a 5-year bureaucratic lead time into a matter of months. Sometimes it's to build where local regulation would outright forbid it, rather than expedite the process.
The thing is that this bureaucratic lead-time is entirely manufactured. It's not actually a natural law. The state can bypass it anytime it pleases and and pass the buck to pick up the mess. The obvious contemporary example is just how quickly data centers have been built, but it's a truism in general. Never underestimate the power of the state deciding to ignore its own laws, and its natural god-given right to do so at any time.

I'm not learned enough on the topic to really comment on it but I appreciated the diagrams and the simple fluid prose. Overall the meta lesson reminds me of the building adage "measure twice cut once".
