> there's an unsupportably growing number who are quite capable of supporting themselves but demand others do instead.

i dont believe this to be true (tho i'd like to see any reliable sources).

I find it more likely that a small number of people control so much "productivity" that the majority must either be "coerced" into cooperating in order to get some of the crumbs, or that they lack the basic resources to dig themselves out of the poverty hole. Its true that they aren't productive enough to support themselves, but i would imagine they would if they had the chance.
