Well thanks for that information.
Actually, to get into any medical school, you have had to have pretty good grades along the way. Hard work can sometimes carry an average intellect a long way, but there’s a point at which the ability required to pass the tests calls for a hard working person with an above average intellect. So, I tend to agree with you that doctors trained in this country have to be above average. (I’m not speaking about the Medical College of the Caribbean Islands.)
Knowing what we know about nepotism, we need to carve out a small exception for those whose parents are so powerful that no school would deny them entry and no school would be comfortable denying them graduation. That does exist in this country. We need to carve out that one small exception, and then we’re on pretty solid ground.
