"New York tells you, above all: you should make more money. There are other messages too, of course. You should be hipper. You should be better looking. But the clearest message is that you should be richer." - http://www.paulgraham.com/cities.html
Of course, founders can make plenty of money. But New York does seem to be unusual in how much it lionizes people who already have lots of money (or least, people who allocate lots of it). I don't expect to see the phenomenon discussed in this blog post change anytime soon.
