Colleges admit legacies for a practical reason. To fund the endowments that bring in top academic talent. Fund research thst drives grants and also helps students get that coveted research opportunity everyone talks about on cc. And most importantly it gives them the funds to offer financial aid, need based scholarships and merit aid.
It’s not a perfect system. And I or not my family did not benefit from this process. Actually the opposite. But I get it. And it’s a lot of misplaced anger imho. The grads fund the future and help maintain the quality of the school. It’s ok. And I would venture to guess many are highly qualified.
