Hmm. I wonder if you could say "if someone becomes homeless in your locality, your locality has failed them". And then rate localities/states by their net loss of citizens that have fallen "outside society". Then begin incentivizing communities to fix these problems. There's only so much a local community can do with limited funds, but while I'm sure the majority of homeless in California are Californian... I would love other states to take ownership of citizens they export/extrude. :s
I agree. From my research, Portugal’s drug assistance programmes for the homeless are quite effective.
For those in more of a poverty trap situation, Finland has done quite a good job finding the right set of policies for their country to bring levels down so far that most Americans would consider them to have “solved” homelessness.[1]
