I would have given 3 stars to this book but coming from a recognised economist as Hernando de Soto I give it only two. Although the book explains in what consists his proposal for the development of the third world, he repeats his idea too much through out the chapters. The examples and methods mentioned didn't satisfy my curiosity for his theory. The book looks more a marketing scheme for selling his idea, which isn't a bad thing, but considering the seriousness of the theme, I would have expected a more professional layout.
After reading this book,go and buy The Myth of Development : Non-Viable Economies and National Survival in the 21st Century, written by Oswaldo de Rivero, a peruvian as Hernando de Soto. Although not advertised as The Mystery of Capital, it has a better book structure and an excellent analysis of the world's current situation and ways to solve it.
