Giving them actual houses would be idiocy, they would be destroyed. Many have been put in dive hotels but it’s been tapering off, the funding dried up. Personally I’d say build managed campgrounds with nice community restrooms and shower houses. Have a small paid staff to maintain the showers and restrooms and enforce basic codes - no building structures, no excessive junk or trash etc. It would provide basic shelter opportunity without costing crazy amounts. A lot of working people can’t afford apartments now, let’s fix that before we throw more money towards people who can’t or won’t work. Hell, I know people who choose to live in campgrounds full-time as their preference.
