This is racist bullshit.
Put American lacks in the same socio-economic and educational environment as successful whites or asians or hispanics and they will do just fine.
It is the scumbag communists that have infiltrated government, academia, and the media that are responsible for this sorry state of affairs.
The communists are mostly white.
Just because a statement appears racist, doesn't mean it isn't true.
The Minnesota Trans-racial Adoption Study looked at black kids adopted in infancy by upper middle class families. The average IQ of blacks is 85. Black children were adopted into white families, and given every advantage of being raised in white middle-class environment. At 17, their average measured IQ scores were 89.
