> The cost of living is always increasing, and the flashy money from silicon valley is accelerating the gentrification of SF. rent-control is a last ditch effort to prevent those who grew up here from being displaced, but in return prevents them from being able to move within the city.
In particular, the bit about being prevented from moving within the city.
There are many problems with SF itself. One of which is the homeless population. But that doesn't feel so urgent. After all, what can we do for drug addicts and mentally handicapped people, outside of putting them in institutions? They're better taken care of here than they would be in most places, and those who live on the streets are at least in a moderate climate. It sucks, but it could be a whole lot worse. And every time I see people give them money, I feel compelled to explain to them that the money won't actually help them, but a sandwich might.
This is a visible problem, especially to tourists, which may be why it's so widely talked about. But there are other extreme problems with the city. Consider rent control, which is only barely mentioned in this article. It's actively destroying the city. Most economists agree about the effects of rent control, too, and studies have shown the negative effects to be strikingly similar to many of the problems SF is currently facing (which will only continue to get worse). http://www.econlib.org/library/Enc/RentControl.html.
How about we solve this problem before SF is just a business center with 0 housing. Then with all that extra housing, we find a place to take better care of our homeless? It's really hard to put them up when you just don't have the appropriate accommodations for it.
