I don't agree with the dystopian view in the OP, but I will say that I notice far fewer people outside in wealthier areas where I live than in poorer areas. I attribute it to most low income jobs not really being bound to the 9-5, so people might be out and about at all hours, especially now that school is out for the summer. It makes these areas feel warmer and closer knit vs. some of the sterile luxury apartments I've seen.
