This is a revised and enlarged edition to the 2004 edition, with an additional chapter on the economics of immigration. I personally find that this edition has been favorably improved as compared to the former edition, while the core of the message remained intact. Dr. Sowell used economic principles to discuss and clarify how the economic issues turned out the way that they are in our present age. The topics discussed by Dr. Sowell, such as medical care, housing, etc., orbit around the core message of "thinking beyond stage one." Alas, as Dr. Sowell so eloquently argued, most politicians do not subscribe to the mentality of thinking beyond stage one, but rather focus on political rhetoric that would get them elected. This book was written for the general public, but I suspect those who are well-versed in the principles of economics will enjoy it as well.
