That's a great point. In the past maybe people wanted to improve the city because that's where they lived, and saw themselves living. There was a comment on HN years ago that I still remember where they compared working in the Bay Area to working in the mines - when people would come over to the New World for a few years to make their fortune, and then go home rich. If you view yourself as a temporary resident, then you're probably not that interested in becoming part of the community and improving the place where you live. Why would you if you're going to take your FAANG money and move to cabin in the woods in a few years?
