This is rubbish. Plenty of nations (i.e. all first world nations) have implemented national schemes of some sort, and none of them suffer from the stuff that you read about coming from the right's bullshit machine. Maybe you're right though, maybe the fact that the US is one of the most corrupt nations on Earth and that its citizens are remarkably comfortable with this fact, means they can't do health care. That's got nothing to do with the concept of nationalized health care and definitely not with regulation in general, but is rather a consequence of an irresponsible citizenry and their terrible social organization.
