Can we discuss health care without the science fiction and doomsday scenarios?

I realize that the USA is used to looking inward for solutions, but other governments are solving these problems, better, today.

Every discussion I have with Americans about healthcare leads directly to these imagined totalitarian futures, as if "everybody" knew that this was what happens. I don't understand it. Where did you all learn this narrative? Was there some nursery rhyme about the evils of socialized medicine?
