Why would you believe the AMA's line on this? Do you think the professional association that represents all doctors, one of the highest paid and influential professions in the country, has no power to control the amount of residencies are funded by the government? They have no reason to increase the number of doctors, absolutely none. They benefit in every way from having constrained supply.
By the way, that expansion of 15000 residency positions barely puts a dent in the number of doctors we are lacking[2]. But yeah, a press release from 3 years ago really absolves them of guilt for sure.
