Grauniad Guardian: Why is Thomas Piketty's 700-page book a bestseller? I like Thomas Piketty’s Capital in the Twenty-First Century a lot. It follows Larry Summers’s advice – which I have always thought wise--that the further ahead in time we want to forecast, the further back in time we should look. It deals with very big and important questions. It takes a broad moral-philosophical view, rather than a narrow technical-economist view. It combines history, quantitative estimation, social science theory, and a deep concern with societal welfare in a way that is too rare these days.
