One is the observation that first- and second-generation black immigrants have much higher share of college admissions than their share of the black population, despite similar socio-economic status to African Americans with longer family history in the US.

Isn’t it obvious? Children of immigrants do way better. Children of Asian households do way better than other ethnicities, and children in impoverished areas do a lot worse.

All of this is cultural and anyone who thought I implied race — which looks like you did — is a moron and a racist.

IMHO this whole thing is environmental.
