Haven't read the ruling, but someone on CNN just said it permits the use of socio-economics as an admission criteria. I suspect this is how racial diversity will continue with admissions. It may be better this way.
Depends on one's definition of better. In theory, it's a more ethical/accurate solution. Many recent immigrant families were solidly working class with modest incomes until the children attended college and became professionals. But instead of socioeconomics, race alone was somewhat of a dominant factor for competitive college admissions.
In practice, California's Prop 209 has proven that Black student enrollment at elite universities will likely crater post- affirmative action. UCs have recruited strenuously over the past two decades to improve diversity, so it's not quite as stark as it was in the late 1990s after 209's passage.
I actually believe the elite private universities had
de facto racial quotas; but I still believe in affirmative action
at this time to ensure campus diversity. The obvious problem is that admissions is a zero sum game. If judging just by the numbers, there should be a sweet spot in between what the Ivy's do versus what UC Berkeley and UCLA currently do.
I LOL'd when Mike Pence told NBC News that affirmative action was necessary 50 years ago, but not today. Society has come a long way in that time, but the work continues.
