I am not disputing that everyone needs medical care...at least to some degree. If you don't like your nose, or your boobs, I think that is on you. But if you are suffering from something that affects your quality of life, then you should be able to get attention.
I am disputing the efficiency of any governmental system to handle such things.
Before we embark upon another government system, (The federal government is a top three employer in this country the last I looked) we need to address all the factors that have driven the cost of care up so much.
Also, we give a lot of lip service to curing various diseases, but, in practice, we want to sell treatment rather than cures.
