The easy (and right) way out was to hire the most competent doctors, not the blackest doctors. I don't want more black doctors, I want the best doctors, regardless of their skin color. If you want more black doctors, you should train better black doctors. However, if you're going to do that, don't be surprised when white trainees band together to work harder too. If it's fair for your side, it's fair for every side.
I have no idea why we went backwards from "discrimination based on skin color is never okay" to "it's okay if they're black" but there's no reason not to simply recognize the mistake, fix it, and move on.
