Dr. Sowell discusses this at great length in his excellent book “Black Rednecks and White Liberals”.
As he states, if this behavior and social state is due to a legacy of slavery, why did it not manifest itself until 100 years after slavery ceased to exists (Discussing the marked swing upwards of black crime, family issues, etc in the 1960’s...)
He is reviled by the left, as a black man who applies intelligence and logic to the analysis and discussion of these issues, as opposed to racism and emotion.
In the interests of a rational consistency and non-hypocrisy, I am trying to stop all of the “IKAGO” excuses in my arguments/debates, but Dr Sowell is one of the very, very few for whom it is almost impossible not to make an exception. Unfortunately when it comes to running a society and setting policy, the exceptions only prove the rule of the vast majority.
