The families who live two and three to a housing unit are the ones who qualify for as much existing welfare as the UBI would provide. It would be trading food stamps for cash but you have to expect most people are still going to buy food.

Replacing housing assistance with the equivalent cash might even reduce rents because then people can decide they would rather live in cheaper housing and use that money to go to college.

The whole thing with a UBI is that unless you make it more progressive than the existing system, all you're really doing is replacing vouchers with cash. If you do make it more progressive (i.e. provide more cash than you would have provided vouchers) then you get the same economic consequences as providing more vouchers (i.e. possible price inflation), but it's still more economically efficient than providing more vouchers, because then people can choose between college or better housing or better medical coverage etc., instead of having the government decide for you.
