Public transit and public places will continue to decline in cleanliness and quality for as long as the rich suck resources out of local municipalities.

They do the same things with public schools (pulling educated teachers to teach in private institutions) and with medical care (pulling physicians into private concierge practice).

If all the rich people had to take public transit and send their kids to public schools, they'd start investing money and (human) energy / capital in making the public infra better.

The investment of resources by rich people into their own private enclaves is entirely rational and can be solved only by wealth taxes that preclude such action (by making it impossible).
