I can't agree with this. I've also lived in SF for the last 30 years and by my lights a simpler, more effective policy would be to roll up the red carpet that was rolled out to tech companies. I don't consider the problem to be one of inadequate supply. I consider the problem to be one of excessive demand from one class of higher-compensation workers more-insulated from market forces (tech workers) out-competing another class of lower-compensation workers less-insulated from market forces (everyone else).
