Between the lawyers and the bleeding hart criminal lovers, they have made it extreemly expensive.
Joe has the right idea, put them in tents and feed them cheep sandwichs. After all, they are criminals.
Joe came up with a new idea. Put the homeless GIs in prison. Fence and put the criminals under the underpasses. Then the vets will have nice comfortable beds, good food, and great healthcare. Sounds like a win-win deal.
