It is impossible to integrate blacks into the American economy.
The average black IQ in America is 85, that is a full standard deviation below the white or asian IQ. 50 years of head start and heroic efforts on the part of educators and sociologists have been unable to change this one bit. IQ is genetic and there is no way that blacks can ever perform at a sufficiently high intellectual level to attain quality jobs in a modern economy.
Still, this is better than the average IQ of Sub-Saharan African blacks, which is 70.
Their only recourse is to destroy, rob or steal. Like the Visigoths who were allowed to live in Rome, but did not enjoy the same high standard of living as the Romans. They became jealous of the Romans and brought down the empire - after first sacking Rome.
Blacks blame whites for their lack of achievement, while the simple, documented and proven fact is that they are intellectually deficient and there is nothing that can be done to fix this defect, ever.
Furthermore, there is some substantial evidence that standard IQ tests are insufficient to measure the true intelligence of minorities, because A) the culture of minorities often disparage the studies required to succeed on those tests, and B) the tests are not written with minority culture (and subsequent learning concentrations) in mind.
I don't necessarily buy your first premise, that there is a race-based difference in raw intelligence, and I DEFINITELY reject your second premise, that intelligence is required to integrate.
