Question: Review: I was actually looking for a book on economics... This book is more of a conservative rant. It's not so much that I disagree with what he says so much as the fact that its all politics and very little economics. Buy this book if you want to hear how much the author thinks liberalism stinks... not if you want "Economics in one lesson." I definitely feel like I got tricked into buying it.
