Downtown Slime
Just why is there so much slime on the streets of downtown SF ? Because the city houses its parolees near downtown, and nonprofits own an inordinant number of buildings, in which they house people who could never otherwise be able to afford living in SF.
Why are ex-convicts and junkies inflicted upon visitors? Because no other neighborhoods want these people, and tourists don't vote -- except with their tourist dollars. So unless tourists vote their dollars elsewhere, and let city officials know that's why they're doing so, downtown will be plagued with the social problems that other neighborhoods (and towns nationwide) are strong enough to purge. They're all here.
Sure, it makes sense to house low-income hotel workers near the hotels. But for all the other people who wouldn't otherwise be able to afford living here, especially the ex-cons and junkies, there are less expensive places to house them than in prime real estate. The liberals pat themselves on the back for their tolerance, as long as the products of their policies are living in someone else's neighborhood.
