If the freshman class at Harvard University ends up being 30% Asian and 10% Jewish, maybe it's because people in East Asian and Jewish cultures value education more than people in other cultures. In that case, why isn't it fair for an educational institution to cater to individuals who have been raised to value education?
If some minorities (and let's not dance around the issue; we mean black people) are underrepresented at these institutions, that is a wake up call. It means that the public school system in our country has, in aggregate, failed black children and that decades of racial injustice have forced black people into self-perpetuating cycles of generational poverty. It doesn't mean that Harvard is being racially discriminatory.
