> We see that as soon as people get some money and autonomy, what do they do? They isolate. People spend a huge premium, such as business or first class plane tickets, stadium box seating, vacation retreats, man caves, etc. to isolate from other people.

The low quality/safety of public infrastructure could be to blame. Why would anyone use unpleasantly hot and smelly public transportation, full of loud and potentially shady individuals, without any security around in case someone creates a commotion - when they could just pay a little bit more and not even worry about any of those things?

Why would anyone go to a public gym with a tiny shared space, number of subscriptions that far exceeds the capacity of the place, and deal with unpredictability of whether or not there will be room to train - when they can build a private gym and train whenever they feel like it?

Why would anyone stand around in the crowded "fan pit", having problems even moving because vendors sold more tickets then there is capacity, wait in the line for public bathroom, wait in the line for drinks, make yourself a target for pickpocketing, etc. - when they could just buy a VIP seat, enjoy their time, and go home?

People will stop isolating themselves when not isolating stops being so unpleasant.
