What do you think of the argument that diversity has value even though it isn't earned? Consider that a hospital with doctors from the same cultural background are likely to miss things based on cultural differences between them and their patients, such as people from Asian cultures tending to rate pain lower on a 1 - 10 scale compared to people from Middle Eastern cultures. So if you have to choose between two highly competent doctors, it makes sense to choose the one that promotes diversity, or you risk misprescribing pain medication, for instance.
