That the middle class has had it up to here with insane left wing politics and social programs, and has fled San Francisco, leaving only the very rich and the very poor who both love those programs?
SF housing prices and apartment rents are sky-high because SF is a desirable place to live. So much so that 16,000 households who make $150k per year or more have moved in, and a similar number of households making less than $150k per year have moved out. So we are seeing the exponential creation of a glittering enclave, with remnant pockets of poverty. (ghetto people, service workers, however you want to slice it)
The mayor continuously upholds corporate welfare programs (PG&E monopoly, etc) so I am not sure what "left wing" programs you are talking about other than public housing (which is insane--we need more affordable low-income housing, not public housing--unless EVERYone were to live in it).
The middle class simply cannot AFFORD to live in SF. That is why they fled. Not because if any "insane social programs" that would subsidize them staying.
Do you perhaps mean "Two Census Tracts" ?

This is becoming a serious issue - at least for me. I can't walk through the Tenderloin now without being acutely aware of the severe poverty.
