Marc Andreessen on why cities ended up with $3 million homes, public housing, and no middle class "There's a French geographer who has the best analysis on this, a great book called Twilight of the Elites. If you replant the commanding heights of your economy on knowledge work, you're going to slam basically all economic growth into the cities" "The cities become a magnet for two kinds of people. The highly educated elite who can afford $3 million houses, and then public housing. Who's squeezed out is the entire middle class. If you're a cop or a firefighter and you work in Palo Alto, you can be commuting 3 hours both ways just to have a house and afford a family" "You look at the cities and there's lots of dogs, very few kids. You can't buy a house, you can't have a family. You've ejected the middle out of the cities into the countryside, but you've deindustrialized, so there's no new economic activity happening in the countryside"
