I've always thought that this is something basic that we need to address as part of any health care reform.
We can't afford to give everyone unlimited health care, so how do we determine the limits?
I assume that a lot of socialized health care systems end up using waiting lists, perhaps based on the patient's age, treatment cost, and probability of a positive outcome, with the option of going outside the system and paying for more/quicker care, for those who can afford it.
One person I discussed this with assumed that there was plenty of money to give everyone care as good as billionaires get. I don't assume that's true. Has it worked out that way anywhere else?
