One of the frustrating things about being American is that you're expected to understand capitalism and free enterprise economics from birth. This is hardly the case. Supply and demand is the cliche that everyone knows, but most only understand the demand part. Americans learn very quickly how to be consumers, but based on our personal and national debt few of us ever understand the supply side. Well here is your chance to learn the basics for significantly less money than taking an economics course at your local college. Preston McAfee has written an economics textbook and released it under the Creative Commons license. The book is, from what I have read so far, well written and very straight forward. But best of all it's free. And free means that you can use the $111.50 (marked down of course) you would have paid for a "real" textbook and perhaps pay against the principle on your 29.8% APR VISA card. And all this understanding and extra money will in return get you more of the other free.
