On my way back from the Happiest Place on Earth, I bought a book from the airport (Why do those little shops always have such good selections?) called The Price of Inequality, by economist Joseph Stiglitz. This book is rich in economically sound explanations for inequality and why it sucks for everyone (and isn’t merely a moral failing of the poor themselves.)
At one point, he says a few things about the impact of education on poverty that underscore the idea that education isn’t the end-all be-all to ending poverty.
