"WE WILL ARGUE that to understand world inequality we have to understand why some societies are organized in very inefficient and socially undesirable ways. Nations sometimes do manage to adopt efficient institutions and achieve prosperity, but alas, these are the rare cases. Most economists and policymakers have focused on "getting it right," while what is really needed is an explanation for why poor nations "get it wrong." Getting it wrong is mostly not about ignorance or culture. As we will show, poor countries are poor because those who have power make choices that create poverty. They get it wrong not by mistake or ignorance but on purpose. To understand this, you have to go beyond economics and expert advice on the best thing to do and, instead, study how decisions actually get made, who gets to make them, and why those people decide to do what they do. This is the study of politics and political processes."
