Have you ever been to Brisbane? Most people move there for the small-town feel; I personally tried, but got out-cashed by a Chinese investor. You're not going to convince them to become San Francisco's housing overflow.

Geographic mobility really is a huge hurdle. A lot of business is becoming centralized around major long-distance transportation hubs, San Francisco being chief among them. Live in Concord, but want to work in Los Gatos? Good luck getting there by train. I lived in the Mission and to get to China Basin was a bus to a train to a bus. I opted for the ten minute drive instead of forty-five minutes of transferring. It's embarrassing how much better we could do so much better moving people around. Right now I opt to drive the 101 south instead of taking Caltrain, even though my employer covers the cost, because it would cost me an additional $10 a day to take other trains/buses to get to the Milbrae transfer, and by the time I've driven myself either to 4th/King or San Bruno I could have already been half way to work just driving the whole way. We need to do better.
