The only thing you are wrong about is the how fungible and fluid the issue is.

This isn't the sort of thing you solve within a limit, a set of bounds; this is the kind of thing that has to be solved at a national or even /global/ level.

I think the only difference between this problem and the European refugee crisis is that at least in the case of the latter it is the tired, the poor, and downtrodden seeking to find the hope of opportunity realized. The 'homeless' in the US probably mostly fit one of these categories: mentally ill, physically ill, under-compensated, under-serviced by and/or alienated from the community.
