At most US elite schools, less than 20 percent is for “non-reserved” seats. Elite schools reserve seats for sports teams (affirmative action for rich white elites with “sports” like fencing and rowing), legacies (affirmative action for rich white elites), related to professors and school administrators (affirmative action for rich white elites), those who write essays on poverty tourism and their work experience in the NGO/white savior/charity scams (rich white elites), and then regular affirmative action (capped at 20%].
So it is a brilliant way to use regular affirmative action for Blacks as a weapon to ensure that rich white elites always win and do not compete with the “deplorable” poorer whites, the Asians and immigrants.
