I don't agree that these people are very many. I think they're extraordinarily rare, but it makes us feel better about ourselves if we think that they are common, and we have managed to rise above the common.
But regardless, if they don't want to be doing anything worthwhile, and they're willing to accept the many social and economic consequences of that (no fun vacations, very hard time finding a partner, no gadgets or new cool stuff, no fancy dinners out), then I'd rather not force them to work side by side with people who want to be there. Give them a universal income, so they can rent a roof over their head, buy somes clothes and food, and then leave them be.
