One thing I would like to discuss though is this line:
The creative class flocks to a handful of happy cities, abandoning the rest.
This suggests that there are entire cities, even states, lacking in creative people. Now I'm sure PG was consciously generalizing, or else referring to the extraordinarily creative entrepreneurs like Musk, Dorsey etc. (creative in the business sense), so I don't want to nitpick.
But what do people think about this? Everywhere I've gone in life I've found creative, dynamic people somewhere in my midst. I know a frequent complaint from the Left is the slightly galling idea that if the capitalists abandoned us, society wouldn't be able to fill the ranks of the managerial positions and keep things going. What do other people think? Have you lived in (developed world) cities which felt entirely stultified and lacking the human capital to make things better?
