I think everyone working an honest job should be payed pretty well (not sure what you mean about 'relative to the supply'), at least enough to have a good life, for sure. Is it too much to ask that everyone have enough to live a good life? Who doesn't deserve a good life because of their occupation? Nobody.

I don't know there's any reason doctors should get exceptionally high incomes (except that in the U.S. they have to pay back exceptionally high student loans for the first decade-ish, of course).

Depends on 'the good life' - we can't lift everyone up to live like a doctor, but it's easy to push doctors down so they live like everyone else.

U.S doctor's incomes are probably influenced by the AMA cartel that keeps good candidates from earning medical degrees. After we bust the cartel, we can let the chips fall where they may. My hunch is that doctors would be paid more like veterinarians if the market were freer.

On some level, a job's compensation is tied to the challenge of the job. It's more difficult to perform good medicine than it is to be a cashier, we should expect doctors to be better compensated than cashiers.

By "relative to supply", I mean that if there are far more than enough doctors in a given region or scenario or specialty, the price could go down and it would be fair.

If you don't think that doctoring should earn especially high incomes, then you have not seen a doctor work, and perhaps you've never been gravely injured.

If you don't think that trashmen should earn especially high incomes then you have not seen a trashman work or perhaps you've never produced trash.
