The AMA doesn't care about doctors any more than the AARP cares about seniors.
The number of doctors is controlled by the extreme expense of educating them. Luckily we can attract foreign educated doctors, but they don't speak good English, and not a few end up terrorists.
Another thing that is challenging the number is how many women MDs we now have who do not want to work the kind of hours men were wont to work. And the fiftyish docs now plan much earlier retirements.
I've known my share of engineers, too, who partied when they should have been memorizing pathways for organic chemistry. Make a C, lose out on med school.
Of course, there's a lawyer on this thread who knows that you don't have to take any math or science, can major in Queer Studies, and still get into a law school. That's how so many cowardly losers become lawyers.
I hope you didn’t expect anyone to actually read that stream-of-conscious bowlsheet.
