You're asking for evidence of no corruption in a totalitarian regime? Are you for real? By their very nature, they're corrupt. What you're describing is global totalitarianism. There is none. Sure, we can make any number of predictions, and that's fine as far as it goes, but don't ask anyone to behave as if theoretical possibility were absolute certainty. Why should they? As far as the medical establishment charging a fee for it's services, that's tangential. They power they wield is not one born of corruption. The power to save lives and alleviate suffering is hardly evil.
