My college economics courses, filled with perplexing theories like the paradox of thrift, GDP and Keynesian fiscal policy, were completely refuted in this excellent free-market textbook. Economic Logic focused on important, real issues like business profit-loss statements, entrepreneurship and the advantage of saving -- something my college professors never even touched.
Although I am not currently a student or professor, I thoroughly enjoyed learning economics "right." I have found it helpful in gaining more insight in running my business -- as well as the wisdom of fiscal conservatism in our government policies.
I highly recommend professors use this text in their economics classes. And students, if your professors don't use this text, get it for yourself so you can really understand the concepts and principles of sound economics.
The text is suitable for anyone with approximately a high-school education (and I'd love to see it used in actual high schools). As such, it's well adapted for self-study.
