This is a bizarre take. The suburbs of the Bay Area are often wealthier and better run than the cities. In fact, it's true of most major cities. The urban core is likely lower income and the surrounding suburbs are where the wealthy live.
Kind of weird to talk about "living on a bunch of credit cards" when it's the cities who seem to burn cash with little to show for it.
But look at the trend post-Covid. It's basically reversing itself. San Francisco is going be completely screwed by the exodus of workers who live in the city and commuters.
It's one big cycle, people moved to cities during WW2, then out to the suburbs during the 60's. Then back into cities in the 90's, now back out in the 2020's.
