Well, I'm not arguing that we should be *given* housing and food as a matter of course, but let's look at the scenario:
You get food. Nutritionally balanced, but nothing fancy. It'd probably be like those food packets they make for starving kids - Rice, cornmeal, chicken powder for protein, and dried vegetables for vitamins. I tried some of that once. I wouldn't want it to be my breakfast lunch and dinner 365 days a year.
You get housing. A tiny little apartment in a soulless cement block building somewhere. It has a bathroom, and a bedroom, and a portable stove to heat the food packs. It'd basically be a jail cell without bars.
You're saying you wouldn't be motivated to go make money so that you could buy *better* stuff than that?
And by the way, as far as filling the time with drugs, hey, drugs cost money, which means they have to get it somehow.
Come to think of it, what would probably happen is that employers would be forced to start paying decent wages and stop treating their employees like shit, because the employee no longer has to worry about starving and being homeless if he stands up to his jackass boss.
Of course, such a move would have to be made only after we repeal NAFTA and GATT so that companies can't just outsource their jobs to countries where people still ARE afraid of starving to death.
