Nigerian-Americans are perhaps the most-highly-paid and successful demographic group in America today. Look it up. Higher median income than Ashkenazim!
But yes, West Africa may have had good reason ...
You are moving the goal posts. From community and civilization building to salary. And you are also cherry picking data. Those are highly skilled Nigerians selected specifically for their skills. I don't dispute some of them earn a lot. And this may well be reflected in the data. But we were talking about the West African phenotype, which reverts to the mean culturally, no matter where on earth and no matter which time period.
