Yes, r > g. So What?
质疑皮凯蒂关于r>g是资本主义核心矛盾的论断，认为其预测和全球资本税建议缺乏说服力。
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.
