Homeless situation....

Would this plan for providing housing include illegal aliens, like the plan for providing healthcare for all?

Because if we do that, it seems kind of obvious that we are going to attract more illegal aliens. The U.S. will become the Portland/SF of the world.

Well, to address your fetish like obsession with this one aspect of the discussion, sure. I mean, that way ICE could much more easily find and deport the ones who are a problem in terms of crime and who aren't gong to be considered for asylum or any path to permanent residency. The Immigration courts could have an address to send their summons to. Employers would have a location to fill the square in the 1099 forms and Social Security would know where to send their yearly statements. The kids would be normalized into a permanent school setting allowing them to socialize with other students and assimilate to the American culture. Home Health Care workers would be able to track the children and make sure their immunization was up to date.
The savings on all of the administrative costs issues above would more than cover the costs of that particular aspect of the program.

Does that work? Can you stop the attempt to thread jack this into a purely political discussion of a separate issue now?
