The AMA has been arguing for increased medical school seats and increased GME funding for about 20 years now. There have been 27 (!!) new medical schools opened in the last 15 years, in large part driven by the AMA in its capacity as one of the two primary stakeholders in the LCME, which accredits allopathic medical schools.

1 out of every 7 medical schools currently active in the US was founded in the year 2010 or after. That's a veritable bonanza in medical school creation, facilitated by the AMA.
