Many countries have single payer healthcare systems and that has nothing to do with fascism or communism.

Healthcare is rife with asymmetric information by its nature. Doctors and nurses understand the medical services they offer much better than most patients. And privatizing insurance makes this worse. Now not only is the service itself opaque to patients but even the fees that they will need to pay for it.

But I also appreciate your point of view and it is good that PPO works decently well for you.
