Charging for saving lives. Price discriminating to save lives.
What happens when they make a mistake in what someone is able to pay?
EDIT (I tried replying but can't yet): The basic solution to make medicine cheaper is supply more medics.
In Chile anybody who wants to be a doctor can go to some medical school and make a pretty decent wage (but less than 20x what an American doctor makes) and help people in some role, some specialty, if that's what she really wants to do.
No quota on helping people.
And they get better results, lower infection rates than American hospitals, longer life expectancy, and medical school is shorter and much cheaper, like night and day. In particular maternity care is like the best in the world--I can't corroborate that but I've heard that.
Lowest medicine costs in the OECD, blows every other developed country out of the water. America is the most expensive and Chile is the cheapest.
