I currently live in San Francisco and it's all true. Way too much of this city is filthy and full of crazy homeless people. Poverty, theft and violent crime (particularly in East Bay) are just through the roof.
Liberalism prides itself on being tolerant of others, and while to a certain extent that's good, we must remember that certain things should not be tolerated. SF is the most crime tolerant city I've ever been to. It seems as if the police don't even care about the state of the city. There are people living in tents sh*tting on the streets within blocks of some of the most expensive real estate in the world. It's absolutely insane.
Word on the street is that the Bay Area has slowly started to lose people, which makes total sense. Who in their right ming wants to spend 4000 dollars a month for a shoebox when there are smelly homeless heroin addicts living in a tent outside their door?
A lot of cities have problems, and there are many wonderful things about SF too ( I don't mean to trash it too much
), but it seems the disparity is only getting worse.
