Allow me to clarify, just to make sure I'm getting your message clearly:
Are you saying that a graduate of a foreign program, specifically medicine, is less well-educated than a graduate of an American program? If so, I agree wholeheartedly. Americans train the best doctors in the world
I'm assuming, per your example, that you're NOT saying a Chinese immigrant who went to Hopkins has some inherent intellectual deficiency.
You also seem to be saying that foreign students are not any MORE smart than Americans, simply because the foreign students we see are the "best and brightest," and thus we know there isn't some farmer in Mongolia who has the potential to get a 66 on their MCAT and 450 on Step 1. Okay, I'll buy that...
Sounds pretty reasonable to me, assuming I've got it down.
