Query: Casual reading, not for serious readers

Now I understand why this book is popular. A serious book can't be that popular. If you have taken the economic 101 and scored above B, you will agree with me.Mr.Friedman obviously lacks of even basic training on economics to handle this topic. He approaches to the topic the same way he used in his another famous but not serious book "Lexus and olive tree". Really shallow!That is because he doesn't have the training to digest enormous volume of economic researches, papers, and data available.Yes. He is sharing with you a lot of stories. He does travel a lot. But he is rumbling. Lot of stories are barely relevant and too lengthy.Bottom line: if you want a casual reading and are satisfied to show off to your friends some strange stories, buy this. Otherwise, use your money to subscribe "The Economist" or buy some books written by Paul Krugman.
