this sounds nice, but neglects the fact that (1) materials cost has gone up and (2) zoning requirements exist. (1) means its just more expensive to build overall, and (2) means that a lot of proposals for apartment complexes get voted down.

Supply constraints are a symptom of the problem, which is housing is a huge leveraged investment for many. You generally won’t get policies for building more when it negatively affects the finances of a majority of voters

Not if private equity just snatches it all up.

Yes build more. Also regulate the oligarchs until they no longer exist.
