London: "You should have been here 150 years ago" is essentially "you should be more aristocratic". I think that signal is strong in London. I have been at dinner with friends who started arguing about how far they had to commute on the tube (as a proxy for social class.) The English pretend to the world that it doesn't matter but it seems to matter deeply to them. This seems to be an English hidden rule; that is how the discussion started.
You hit the nail on the head: This whole essay is based on a false premise (which nonetheless is strongly believed by PG). Cambridge only seems to be a "smart" town if your social group consists of people associated with MIT, and you're only likely to end up in that social group if you were part of the middle class when you moved there.
"... Melbourne: You should spend more money on clothes ..."
No it's more like...
Melbourne: You live in the sports capital of a sports crazed country. You should go to the footy, the cricket, tennis and don't forget some new duds on cup day.
Tel Aviv: You should be moving faster. A lot faster.
Dublin: Be wittier then smart.
Melbourne: I agree. Its a confused message that definitely has to do with sports not clothes.
Sydney: You should spend more money on real estate.
Melbourne: You should spend more money on clothes.
London: You should have been here 150 years ago.
Davis, CA: You should leave Davis, CA.
