Yes, r > g. So What?

Abstract

Piketty argues that r > g is the "the central contradiction of capitalism" and that it will lead to an "endless inegalitarian spiral." As a result, he argues for a new global tax on capital. In this brief essay, I explain why I am not persuaded by either his prediction or his prescription.
