I'm not sure if the 6,355 in the supportive housing contributes to the 7000 "homeless" statistic, but dollar spent per homeless person seems like a measurement that's at best misleading and at worst a propaganda soundbyte.

If SF isn't able to handle the issue themselves, then why shouldn't they use their money to help them? Should it only be the poorer areas of the country that handle the issues that the rich areas cause?
Poverty and homelessness are complex issues, especially when regional inequality gets involved. If a certain city or state is too expensive for the poor to comfortably live in, why would it be bad to send them somewhere that would be easier to live? Why could it not be part of a number of steps to tackle the problem of poverty and homelessness?
