It sounds like the same story being repeated all over the world. There was someone on comments here on another thread talking about how this is a problem in Ireland now as well. It's not just SF in the US, it's all over the place. A friend recently told me about his search for a place to rent in rural western Washington and they said it was just impossible to find even a one bedroom place under $1800/mo even in this rural area where incomes are much lower than in the urban centers like Seattle and Tacoma.
