Well, since the population of SF (like Manhattan, Tokyo, Paris) hasn't been growing much over 1%/yr for the past 30 years, I'm comfortable with history. You can have enormous growth in established centers (not bombed out) if you don't have property rights. See Beijing or Shanghai. I've seen 30-50x 30 story apartment blocks go up in a year. I don't mean 1 block like that. I mean 5 or 6 just looking around. Each one has it's own school, fire, policestation, and is designed for a subway stop and a mall underneath. It's amazing what a centrally planned economy can do!
