It is true that housing is too expensive and this is a primary cause of homelessness, but I can't accept the logic that just "building more housing" is the solution here. Sure, adding a bunch of empty houses to an area will create a downward pressure on prices, but at best this is temporary. When I look around, the densest cities are also the most expensive to live in so making places denser will only hurt low income earners who want to live there even more. The reality is if we want low income families to be able to live in desirable places the only solution is public subsidization. Just handing this problem to the land developers and removing all zoning restrictions is not going to fix anything in the long run.
