Are people really being gentrified onto the streets? You really think high-functioning people are becoming homeless for want of $3000/month income to pay rent?

Are people really being gentrified onto the streets? You really think high-functioning people are becoming homeless for want of $3000/month income to pay rent? I doubt this very much; if I became unable to pay rent in the most expensive city on the continent, I'd move to a city that costs 20% as much before I moved onto the sidewalk. Gentrification and land use policies are real problems in SF, but homelessness I think is mostly due to addictions and mental illness, not really the lack of adequate housing.
