It’s a math question. East Asian students are overrepresented at some elite universities, leading some — particularly those with foreign passports – to fight affirmative action. The Supreme Court recently upheld preferences for Black and Latino students, but challenges from Asian counterparts say quotas discriminate against better-qualified applicants. Even so, younger Asian-Americans support affirmative action, which could even benefit underrepresented Cambodians and Laotians. Any perceived harm suffered is legally hard to prove, and the high court’s ruling suggests “holistic” admissions processes will remain the solution to a long-vexing problem.
