All of those are political non-starters.

I think you're not considering everything. Or maybe it's because the weeds can get very deep. I'll approach one thicket here...

I was traveling and encountered some Canadians. Their daughter is in med school in Canada. Costs ~$400 (Canadian) per semester. She is going to become a doctor without the massive debt most med students in the US incur. Therefore, she can have a smaller salary and still be living quite well. We didn't get into insurance, but I suspect the laws are different in Canada regarding malpractice insurance. Two relatively simple things, and you've reduced how much doctors need to be paid to be doctors.

We need a complete system overhaul, and it will need to be phased-in over a generation or so (unless we're going to pay-off current doctors' loans in exchange for lower compensation rates, which is an idea...).
