Good Lord. I hope that is not an indictment of ME reading a “Paltry” three of his books...I would presume having done that, I am in the upper five percent of nearly any demographic slice you would make!!!
Indictment? Of course not - more of an incitement to get you to take a trip to the library and see what else Sowell has written besides the three titles you mentioned. Those three are among his best, but there are numerous others which can be compared with them and some might even be better. When I first tumbled to how insightful Thomas Sowell was, I went to the library and got as many of his books as I could - and back then he hadn't written half as many as he now has to his credit.
