You are ignorant beyond comprehension. I have not been in a hospital in years and pay out of pocket for my care. Most hospitals could never survive without Medicare as most people in hospitals are elderly and do not pay out of pocket. But I guess that is fine with you if every hospital goes out of business.
Every public hospital, of course. Why should I be forced by the government to pay for other people's problems?
Private hospitals would do just fine with no public hospitals around.
You should try looking into capitalism sometime. It works.
