Then ... he explains why, over the past two hundred years, wealth has diverged across the planet in the manner that it has and why the poorest nations have been so markedly unable to escape the cruel vortex of poverty. The groundwork laid, he explains his methods for arriving ... at a holistic diagnosis of a country's situation and the options it faces. Rather than deliver a worldview to readers from on high, [the author] leads them along the learning path he himself followed, telling the ... stories of his own work in Bolivia, Poland, Russia, India, China, and Africa as a way to bring readers to a broad-based understanding of the array of issues countries can face and the way the issues interrelate.
