Abstract

In this article, I present three key facts about income and wealth inequality in the long run emerging from my book, Capital in the Twenty-First Century, and seek to sharpen and refocus the discussion about those trends. In particular, I clarify the role played by r > g in my analysis of wealth inequality. I also discuss some of the implications for optimal taxation, and the relation between capital-income ratios and capital shares.
