I have to disagree with that. It's possible to set up a single payer system that everyone pays into as we do with insurance. The good part about that is government isn't on the take and marking up the rates due to artificial inflation. If they were, they would have to answer to the citizens, and not the stockholders. The great thing about this is you don't have to enslave anyone, because everyone will be working on the same system that's employed in the private healthcare industry, which isn't slavery now. Switching providers from Met Life to Fed Health shouldn't be that big of an ordeal.
IMO, the real problem people have is the FUD being spewed by the healthcare industry because they stand to lose a lot of profits. They might even be fighting for their very existence, but I don't think they're entitled to exist when they fleece their customers, collude with competition, and refuse to employ price control. Why try to act right and serve customers better when it's easier to scare people with talk about "death panels", "enslavement" and "communism". Hell, it might cost a bit to lobby, but it's cheaper than changing how you do business.
