There have always been natural meritocracies of talent and skill. In the Western world, the idea of meritocracy has been a conscious push-back against aristocracy, inheritance, class, prejudice, and patronage.
These days, some complain that meritocracy is a cover for sexism and racism. The history: The New Ruling Class. A quote:
...Peter is not at St. Paul’s because his parents went to Harvard; as he makes clear to Khan, he is there because of his hard work and academic achievement. Here we have the meritocratic delusion most in need of smashing: the notion that the people who make up our elite are especially smart. They are not—and I do not mean that in the feel-good democratic sense that we are all smart in our own ways, the homely-wise farmer no less than the scholar. I mean that the majority of meritocrats are, on their own chosen scale of intelligence, pretty dumb. Grade inflation first hit the Ivies in the late 1960s for a reason. Yale professor David Gelernter has noticed it in his students: “My students today are…so ignorant that it’s hard to accept how ignorant they are.… [I]t’s very hard to grasp that the person you’re talking to, who is bright, articulate, advisable, interested, and doesn’t know who Beethoven is. Had no view looking back at the history of the twentieth century—just sees a fog. A blank.”42 Camille Paglia once assigned the spiritual “Go Down, Moses” to an English seminar, only to discover to her horror that “of a class of twenty-five students, only two seemed to recognize the name ‘Moses’.… They did not know who he was.”
