There's another housing problem which maybe sounds ironic but I would argue that due to land costs, and tastes.. new housing in general is "too nice" compared to old housing. That is - the size, materials, appliances and finishes of housing have all got dramatically better in my 40~ year lifetime. No one builds utility housing anymore, its all aspirational.

So for example, my parents & in-laws live in SFHs worth like 300k built in 1970-1990 era. The problem is that anything of comparable size built in the same town or neighborhood since is now going for 800k (literally across the street even). There is no cash-out downgrade for them to move to a townhouse and put there underused homes on the market. They weren't building said townhouses 30-50 years ago, so all available ones are newer and thus .. too nice. Why would you move to a smaller place for same/more money which also has some monthly HOA/condo fees?

My first NYC apartment didn't even have a dishwasher or full sized fridge. I didn't have an in-unit washer/dryer until I was 35, and it was small/bad. Meanwhile it's interesting seeing the expectations of GenZ moving into apartments with their first job that are finished like the nicest apartment I ever lived in. Then they complain about cost? I can still find my old crappy apartment on street easy, and its rent is only up 50% in 20 years which given wages seems fine. Kids are moving to shiny finishes new rentals in Bed-Stuy for more money rather than enduring the indignity of living north of 96th street in a 2nd floor walk up.
