If anything, I'd argue that diverse access to top-notch college education matters more to society than diverse access just within medicine. And so many of the same things are sought after at top undergrad vs med school (service to community, passion and achievement in your subject of interest, strong academics etc) that the comparison should hold
This is where I will disagree with you. Firstly, there are plenty of other great colleges out there; if someone doesn't get into a top school it isn't the end of the world. Furthermore, medicine is a field where race can have a very real affect on outcome, whereas other jobs it likely isn't that much of a factor.
When it comes to medical school, the simple fact is that a disproportionately large amount of Asians apply, who on average have similar backgrounds, so medical schools can pick some more cream of the crop compared to white applicants. I don't think it is surprising then to see some disparity in the lower end of scores.
I don't disagree with the fact that AA in undergrad may unfairly target Asians, as pseudo-AA (such as legacy, athlete etc.) may still help whites get ahead.
Neither are blacks from the African subcontinent: Ghana, Nigeria, etc. Much different than blacks which affirmative action was meant for.
Do you have any data on what proportion of the black students at medical schools are African vs. African-American, and their corresponding stats?
Actually the link does - if you read it.
I'm saying the medical school can assign value to their background on their own terms. Some may want African immigrants, some may not. Your link is referring to undergrads as well, where the dynamics can be a bit different. Lastly, your link is fixated on the financial aspect only, not any other type of discrimination.
