It took some digging, but essentially they work in a university town. University towns are basically the apex example "walkable" with good restaurants, good shopping, good services, etc etc etc.
The happiest existence I had lifestyle wise was living in university. It is the closest socially acceptable communal living experience in modern capitalists.
There were stories of colonists captured in Indian wars by tribes, "freed", and they ran away to go back to the tribal group rather than go back to colonial life. You know, Dances with Wolves but in real life.
There was a slight uptick in communalism in the early internet, but the MBAs have stamped out that out hard.
Honestly, for places like San Francisco where Silicon Valley essentially destroyed the communal aspect of the city, all of those tech bros moving away would be good in the long term. Of course it would also take a massive collapse in property values, and kind of like revolution, that's never a good thing.
