Sub-Sahara Africa has no “crackers” or any “redneck” Scots-Irish culture aka “poor Southern Whites” to blame. Sowell’s theory is quite a stretch.It's precisely Sowell's point that African slaves did not bring but adopted here the marginal white redneck culture that black ghetto culture yet embraces.
So, Africa is a high IQ Wakanda paradise then? No violence, theft, murder, or rape there? Somalis only recently arrived in the USA, mostly in Northern States.
What is their excuse?
