As someone who works in SF every day, it does seem that in the last few months the city might be turning a corner – there are definitely fewer tent cities, and general public cleanliness seems improved as well. The cost of these programs must be phenomenal (permanent police presence on the Civic Center plaza, full-time attendants in many subway elevator cars are just a couple examples I've seen near my work), but in a city as rich as San Francisco I think many would say it's a price worth paying to clean up the commons.
