A very good, thorough, book on economics, using events from The Simpsons. A caution, it is a little more academically-written than most nonfiction, but if you have any experience as a post-secondary student, you will be just fine. I was amazed on how accurate The Simpsons depicted economic problems (at least, those used in the book), such as during the re-enactment of prohibition (and beer barons) for which the TV show then showed the result of this regulation - not a ban but simply increased prices of alcohol, and the rise of black markets and organized crime. Note also that the book takes a firmly free-market perspective on economics, so those of you who prefer praise of socialism and central planning will feel accosted during this book. It may be good for you though.
I think the greatest lesson of economics is that you can't have your cake and eat it too. Economic policies have trade-offs. A utopia-fantasy of some that we all can share everything and everyone will have all their desires met will not hold up in economics. Everything has costs, production must come before consumption, people react to incentives, resources are limited, desires infinite, scarcity is forever, there is no free lunch, etc. If you divert one cost from this pile, it will simply transfer to another cost. Make health care 'free', and those costs simply move to another place (perhaps higher taxes, lower health care quality, lower health options, etc).
However, if you have no knowledge whatsoever of economics, I recommend you start with Economics in One Lesson by Hazlitt.
