Capital sparked a fantastic global discussion this year about inequality. Piketty kindly spent an hour discussing his work with me before I finished my review. As I told him, although I have concerns about some of his secondary points and policy prescriptions, I agree with his most important conclusions: inequality is a growing problem and that governments should play a role in reducing it. I admire his work and hope it draws in more smart people to study the causes of, and cures for, inequality.
