Sure, the half that's freeloading off the half that works for a living. Or, to put it another way, the half that's too lazy to steal and relies on the government to do it for them.
A major cause of the problem is people who send their children to government indoctrination centers (public schools) where the children do not learn the facts about capitalism or collectivism, or American history, or critical thinking.
I would say Todd is understating the percentage. I would also say that you are understating the percentage of freeloaders, since public schooling is a form of welfare. Doesn't matter if you're paying taxes or not. If you took food stamps or heating assistance while paying taxes, you'd be freeloading nonetheless. Same with public schooling. Yet many do it, because they went to public schools themselves...and they just don't think. (In two generations at most, they will have stopped thinking about food stamps, too.)
So if I may take the liberty of paraphrasing your post:
"Half This Country Believes In Collectivism" Sure, more than half are freeloading. Or, to put it another way, the more than half that's too lazy to TEACH and relies on the government to do it for them.
