This guy will probably be feted across academia for his insight, even though it’s fundamentally the same argument made in The Bell Curve that gets Charles Murray banned from college campuses. Yes, the cognitive elite is a thing and no, they don’t work at Walmart. There is no answer to this problem, either.
There's nothing in this article that mentions "cognitive elite", it talks about education and skills. You brought that to the article completely on your own.
For what it's worth, I think that there are definitely innate differences in ability, but they're very much overstated and the education system is effectively money laundering for privilege. Education != innate ability in a world where elite colleges charge massive fees and all the selection processes are rigged every step of the way by the middle classes.
I have a decent job because I went to a decent uni, if I replay my life with the same ability and different parents who didn't work hard to squeeze me into the best school in the area or push me to value education I'd have no chance at all to be here now, I would be writing javascript for the local bakery for 20k pa. Good tech companies and finance all hire based on degrees.
