Oh, I must profoundly disagree: at least for MBA admissions, affirmative action is very much alive and well, and arguably even more prevalent than it is in undergrad admissions (if that’s even possible). I can assure you that words business schools take great pains to achieve admissions goals of ‘diversity’ and ‘balance’ - which essentially means affirmative action - while facing the acute problem that while however few highly qualified URM undergrad applicants may exist, there are even fewer highly qualified URM MBA applicants.
But don’t take my word for it. The J. of Blacks in Higher Education published several articles regarding this topic.
