Question: Economics in One Lesson elucidates the basic principles of Economics in a simple, understandable language. If you are just starting out on economics, I would recommend this as your first book. College Textbooks will bore you and treatise like Human Action by L.W. Mises are pretty hard for a beginner.Also, be sure to give this book to your children. Schools don't teach economics, a most important of subjects.With that said, I would like to comment on many 1 star reviews. Notice how they don't comment on the content of the book. Economics is a Science, and it is better to put away your Political Glasses when studying it.

Answer:
Positive
