Sure, but based on when college educated people have their first child on average, the average legacy admitted student in 2024 probably has a parent that graduated in the mid-90s.

I don't when Stanford started being majority non-white, but at least 20 years ago, and probably in the 90s. It was 41% white in 2006. Whenever the date was, it is a benefit that is been accruing to mostly non-White graduates for a long time, and about the time they get to use it, it is gone. It is good for fairness, but don't know that race should even be a part of the winner/loser discussion.
