Sowell sucks.
Whenever someone hits you with the "Listen to me because I deal with facts, while the other side deals with emotion" (an emotional appeal in an of itself) you know you're in for some horseshyt. Our species is divined with the ability of an elevated consciousness, so to say one's opinion lacks emotion is to say its not appropriately human at all. We are hardwired for subjectivity. Its part of the theory that stats often dont lie, but liars use stats.
We know Sowell is governed by subjectivity, because his views dont stray from a strict republican orthodoxy, and "liberals are always wrong/racism is overstated" bellowingd. This of course is an impossibility, and true intellectuals try to apprehend all available possibilities. Sowell is beyond selective.
When it comes to the black experience and the diminished black state, there are a universe of historical and current variables that he dismisses. There's of course the psychological residue of slavery both for the oppressed and dominant, there are public and private enterprises that openly discriminated against blacks during the mid 20th century via redlining and va home loans (a critical period of wealth building in america), there's the spate of riots during the 60s in black neighborhoods which drove businesses from areas that would become economically depressed hoods, there's evaporation of low skilled factory work that disappeared from cities hitting blacks the hardest....
Literally I could go on and on, but the unique experience of the black American is something Sowell hasnt even attempted to analyze with sincerity. His position from jump has always been "racism didnt bother me much, so it cant really exist" type narcissism. Posting videos from 30-40 years ago doesnt help us much. Sowell, like the republican party of last generation, placed a value on intellectual rigor that is today non-existent. Thats why you can currently catch Sowell supporting the likes of George Zimmerman (what does that have to do with conservative politics..oh I know its anti-black thats why). Sowell's work can largely be taken apart by anyone who has taken a community college beginners course in economics and 20th century race relations.
