There was a time when they had a quota capping the number of Jews they would admit. Now they have inverted the meritocratic process to limit the number of Asians admitted. They should have a diverse student body - intellectually diverse.
Though Harvard really isn’t the problem. It’s wrong but it’s a minnow in the ocean. Public K-12 schools are where the real problems are. How many schools in Baltimore where none of the kids can pass the math proficiency test?
The problem is that intelligence is highly inheritable. AND is correlated with earning potential.
So, if you take a class of kids with parents who have self-selected to live in a slum and who can not pass on any love of learning to their children, mix in a fair number of troublemakers and leaven with a lot of ghetto attitude, it would be a miracle if more than a very few had any math proficiency.
Then add in the Politically Correct assumption that all kids are equally intelligent and we have an unsolvable problem.
