You didn't think the 50% admit rate for athletes, 40% admit rate for deans interest ie large cash donors, and 35% legacy admit rate were "the whole think"?
Honestly, the combination of extremely discriminatory, extremely corrupt, extremely predatory and then again discriminated differently by the fact if they are a sportsball player or not is rather amusing and at the same time baffling when observed from the other side of the globe.
Of course it is too late by now, by have Americans considered maybe abolishing all that and admitting students only based on the exam results, with preference given to the kids with better results (or no preference)? And replacing professional sportsball with a 1 lesson/week of general fitness? Maybe then they won't need to get so much debt to study too.
Legacy and donor admissions aren't the gotcha against race neutral admissions that you think they are. In fact, they go hand in hand. It's not a coincidence that the universities with strong legacy preferences all practiced affirmative action. Legacy students actually have slightly better grades and SAT scores than average, but this would unlikely to be the case if they used purely merit based admissions.
