lol i've heard a few ppl pitching a "city for the homeless". build a government subsidized city in the most cheap ass land we can find in the country. away from everything else. free housing free food, nothing fancy. have them do jobs processing food or building weapons or whatever else the government needs. there's cops everywhere, you step out of line there's somebody there to taze your ass. imports and exports is controlled so they can't relapse on drugs.
oh wait, we got something like that... prison. it does a shit job at fixing homeless ppl.
