There is a difference between genetics and eugenics. Eugenics seeks to modify progeny in order to weed out defects and promote certain characteristics. He is not propping up that line-of-thought. He is speaking to the genetic predisposition of ethnic groups. We all belong to different genotypes/phenotypes. I’m ashkenazi. We pretty much run everything and solve big problems. It’s kind of what we do. There was a ton of genetic variation in Africa. I don’t think that Sowell even was attempting to imply less IQ among black people and was showing a similar gradient as compared to other genetic backgrounds. His whole argument is nurture over nature. Systemic racism is just racism. Sure, there was some past redlining, but those issues have been corrected. I had nothing to do with past redlining and my taxes shouldn’t have to make concessions.
