You’re trying to avoid the point.

Say a college decides to admit a less qualified candidate because mommy or daddy is a graduate/famous/a donor. The college does this because it sees the admission as benefiting the college in some way.

The college has the same opinion about admitting a less qualified student from North Dakota or from a given racial/ethnic group. There is no difference.

If one discriminatory practice (“racial boxes”) is unfair and must be ended, then they all are (alumni boxes, donor boxes, fame boxes), and they must all be ended. Admissions have to be fair, for everyone.

Discrimination in all its forms undermines society as a whole. Discrimination in favor of the wealthy is simply another form of discrimination, albeit with more serious consequences than discrimination in favor of the underprivileged.
