I don't understand the hate towards market rate housing. Want the market price to come down? Build more supply. We're so far short of healthy levels of stock, however, that there's no relief in sight with merely-modest pro-housing policies. We need something akin to post-ww2 levels of construction.
The argument I've seen is that basically because we'll never have that post-ww2 levels of construction - building more market rate housing only pushes existing tenants out of the city. You have to usually tear down existing housing and then build new. So, the old tenants get pushed out and then new housing comes in but it's a lot of investment properties and whatnot... So, the cost of housing doesn't actually go down.
If we had post-ww2 levels of housing development but with mixed use residential then I'm thinking we'd have more of an agreement but that's the issue... No one thinks that will ever happen. So, they advocate for more government housing because that will improve more lives of lower income folks.
