I find it astounding that people still talk in terms of "talent". What else, do we still think America is a meritocracy? By and large, people.perform exactly as their socioeconomic status would predict. "talent" is a myth.
If you think the US is a perfect meritocracy you’re a fool. If you don’t think it’s a great deal closer to it than an enormous majority of past and present societies you’re a bigger fool. The same is true of the entire OECD and many countries outside it to greater and lesser degrees.
