Lol. The AMA, AOA, et al are self interested political lobbies. Very little of what they say should be payed any attention to by legislators.
Heres a fact: US med schools aren't better than other 1st world foreign med schools. In fact, some foreign med schools are muvh higher quality than a lot of DO schools and some public MD schools as well.
If you wanna make foreign MD grads from 1st world countries take the USMLE, fine. But no residency should be required at all whatsoever. That's a clear scam for hospitals to get cheap labor and for the pigs in the alphabet soup lobby groups to keep the supply of physicians artificially low.
"But wait, they're addressing the shortage by opening new American med schools!!!'!',?!?"
Great, new DO "schools" that are just a branch campus of another branch campus of an unknown college that is accredited before they even hire instructors who do no research or even have a building (VCOM-S ring a bell?). Yeah, but go ahead and pretend that produces physicians on the level of a Cambridge or Karolinska.
