Any discussion about health care should begin by acknowledging two basic facts.
First, no matter what health care system we have, we are all going to die. At best, medical treatment can extend life, but only so long.
Second, no matter what health care system we have, there will be procedures to extend life that are possible, but not affordable. If an operation costs a billion dollars, you're not going to get it.
For most of human history, there was no health care. If you got sick, you either got better or you died.
Keep this in mind when you hear sob stories about people who died when they couldn't afford treatment.
