SA: racial quotas literaly everywhere + usual college degradation
I imagine:
the old eng. with old-school-british-style retired. He was not a genius, but he could read a tech book.
The new eng. went to college via quotas, become an expert on communist agitprop and bulge drinking. Then he was hired by racial quotas.
He inherited the books from the old guy, but they are too long and difficult for him.
