I think Paul Krugman is wrong today on international trade. For we find him in “plague on both your houses” mode. On the one hand:
…Globalization is only one of several factors behind rising income inequality, and trade agreements are, in turn, only one factor in globalization. Trade deficits have been an important cause of the decline in U.S. manufacturing employment since 2000, but that decline began much earlier. And even our trade deficits are mainly a result of factors other than trade policy, like a strong dollar buoyed by global capital looking for a safe haven.
