> Ever wonder why the cost of healthcare is so ridiculously expensive in this country?
The major point that I make is that physician salary is under 10% of US healthcare expenditure, so that's not why healthcare is so ridiculously expensive here, and driving it to 0 would likely make little overall impact. You haven't made the case that a constrained supply of physicians is the reason why there is a large amount of healthcare regulation in the US. Much of that regulation is to the consternation of physicians as much as it is to those who want to innovate in healthcare.
Finally, part of the reason that 16 of the top 30 jobs are different subspecialties of physician is that those jobs have existed for quite some time and are cleanly delineated into subspecialty. If you were to break out different roles in investment banks and hedge funds similarly, you'd probably not see physicians in the top 30 list.
