Some (SF, seattle) have developed this strange mix of the very very rich and the homeless on the street. Others (Vancouver) see inverted traffic patterns as more professionals (carps etc) drive into residential neighborhoods to work on houses than residents drive out. Suburbs are now industrial zones, places where people go to work. Anyone who can afford to live in the suburb, in a detached house, can live on investments alone.
I ran into a teacher from my old school last year. In my day, the school built doctors and lawyers. Everyone went to university. Now, the kids are so rich that they have no drive. None want to be doctors anymore. Doctors have to touch sick people. How do you motivate a kid who knows he has a guaranteed job at his parent's investment firm, that has trust portfolios that will support him forever?
