>Building new housing doesn’t help now. It helps 15 years from now. If there was adequate construction 15 years ago rent wouldn’t be as crazy as it is today.

I totally get that, but in addition to building more housing, stopping the rent prices hikes would help immediately. There is no reason that the apartment I used to rent 5 years ago for $600 should be $1200+ now, except that property management places can get more profit.
