Then there is the possibility that the authors of the Bell Curve are right. Even middle-class blacks do not in general match other groups in academic achievement. Maybe the same genes that make blacks the fastest runners —and arguably also the slowest—work to reduce the intellectual ability
of black students. But it is not just a black-white thing. Appalachian whites do no betters on standardized tests than blacks.

There is more than just a possibility. That wasn't the only study that was done comparing race and IQ. Some have found that entire populations in Africa have sub-75 (retarded) IQ’s. Although the results of such studies are dismissed out of hand as being “racist” by the PC police, regardless of the truth of their results. Even when put in identical academic environments black students, on average, will do worse then their white counterparts (on average).

Very often black folks graduate high school (those that do) being unable to read or do basic math. It's unfortunate that the didn't get an education, but the bottom line is they can't function as productive members of society without these basic tools. If they don't have a skill-set that includes basic mathematical and reading abilities then they can't be expected to prosper and reach the same economic levels years later.

Not true. AA students average IQ is 85. West Virginia average IQ is 98.7. California average IQ is 95.5 - due to large percentage of recent Hispanic immigrants, legal and illegal. Zimbabwe average IQ is 66. If you break out income per adult worldwide, or go country by country, the single biggest factor is IQ, which accounts for 60-70% of all income differences. And if were to consider U.S. residents by country of origin, country of origin IQ again explains 60-70% of income variation.

Exception: first-generation Jamaicans make more than white Americans. However, second-generation Jamaicans are not statistically better off than any other AA group. Jamaica average IQ (not immigrants to U.S.) of 72.

Of course, Americans of east Asian ancestry (Chinese, Korean, Vietnamese) do much better than AA or whites on IQ, and second generation does much better on income. So there's a lot of regression to mean in the data, where mean refers to country of origin.
