Austin’s Surge of New Housing Construction Drove Down Rents

After decades of explosive growth, Austin, Texas, in the 2010s was a victim of its own success. Lured by high-tech jobs and the city’s hip reputation, too many people were competing for too few homes. From 2010 to 2019, rents in Austin increased nearly 93%—more than in any other major American city. And home sale prices increased 82%, more than in any other metro area in Texas.

Its wild how the solution to housing costs is really just:

Build more housing. Keep law and order.

No it doesn’t need to be “affordable”. Yes rent control is a terrible idea.

Just build more housing.

Note: that the US already has plenty of housing and housing costs basically go up in areas of low crime relative to economic opportunity. If you build housing, but allow crime to rise, you have wasted everybody’s time.

New construction has already decelerated in Austin due to falling prices, which compresses already-near-zero margin on real estate development.

So yes, it really is "just build more housing." The problem is: why would you build more housing as prices fall?

I'm confused by this objection, if you draw a stereotypical supply and demand curve, you can see how prices settle to an equilibrium point. Of course reality has more complications, but I think your objection is 95% answered by a supply and demand curve. You keep building houses when it is profitable. You stop when it is not. This naturally keeps everything in balance.
Sure, so long as the balance involves not housing people which is pretty sick and twisted
I don’t understand your sentence. What’s the subject of the verb “housing.”
The subject is “people”. Parent is suggesting that the equilibrium point of housing supply and demand naturally leaves some people unhoused.
That is the object of the sentence. He is asking who the subject is, in other words the thing or person that is doing the housing of the people. Is it the government? Is it you? I'm currently responsible for housing myself, which is annoying so I would prefer someone else take on this responsibility.

Which isn’t quite accurate as for example people prefer to move out of their parent’s homes while young adults but aren’t necessarily homeless if they don’t.

Basic housing is a necessity, but people also huge homes and 2nd homes etc. So housing policy should therefore be more complicated than simply subsidizing anything you can call housing. Capping the home mortgage tax deduction at ~median home prices for example is probably a better use of government funds.

I think the subject is perhaps an implied "you", "us", or "society". Here's how I read it:

Sure, so long as involves (you / us / society) not housing people which is pretty sick and twisted
