Whenever there's value in agglomeration (ie, all the time), the value of well placed properties just skyrockets, because growth is only going to make that land better. That's why a common recommendation is to up the tax of land as to make speculation with valuable property a bad investment: It's already price like an auction, so higher taxes cannot increase rent prices. The problem is political, as countries with housing problems have a whole lot of individuals have a big percentage of their net worth in housing. Big tax increases would make their property values drop, and they'd be quite upset. So it solves the problem while losing elections.
Instead, governments are happy providing tax advantages to existing residents, in practice making prices go up even faster.
Some might call it housing asset based welfare. Even if you don't like that mouthful another simple example is the University of California putting 4 billion into Blackstone's REIT with "a minimum 11.25% annualized net return through January 2028." That REIT is 90% rentals. So probably at least a few people will feel the squeeze from it.

Social housing in Europe while exists, distribution of it is extremely corrupted process. Applying and waiting will give you something in 5 years or never, you'll know in 5 years. You have to be young couple both employed with perfect portfolio, or whatever the role model in that time and location is. Young couples both employed in desirable city basically don't exist anymore, even if you are after two rounds of waiting suddenly you are not a young couple anymore:) Usually you have to know someone and give a bribe.
Europe has no homelesness, because migrants are housed at hotels at great expense!
You can plunk $10-$20K and get land and a homestead in dozens of states.
Agree with the other comment that overbuilding is a reasonable strategy, but if you look at Detroit downtown (mid 2010s) having an overbuilt downtown is bad too.
It's a hard problem.

In a place where the only jobs to be had are at below-subsistence minimum wage at the dollar store and you have to drive 2 hours to see a doctor, sure.
China managed this quite well with the hukou system, which allegedly is going to be loosened over time, but that seems distinctly unlikely to be understood by the powers that be here in the US.
Did I mention the legions of uneducated anti-Christians who would probably kill me for being queer?
