I must admit, I think Thomas Sowell's excellent book Basic Economics: A Citizen's Guide to The Economy" appealed to me more because it felt more readable to me, and had scads of examples of liberal economic policy that created disasters for some segment of the economy.
But I admit, on issues of race and economics, I am partial to nearly all of his work. Black Rednecks and White Liberals is an excellent work on race relations.
Thomas Sowell is black, and as a result, his arguments carry weight with me, since he knows of what he speaks. I don't think you can go wrong with any works by him, they are all universally good, and he has a large bibliography.
Definitely one of my heroes. (Whittaker Chambers, Joseph McCarthy, Admiral James Stockdale, Phyllis Schlafly, and Thomas Sowell, and my parents,just to name a few...:)
