All economists know that when American jobs are outsourced, Americans as a group are net winners. What we lose through lower wages is more than offset by what we gain through lower prices. In other words, the winners can more than afford to compensate the losers. Does that mean they ought to? Does it create a moral mandate for the taxpayer-subsidized retraining programs proposed by Mr. McCain and Mr. Romney? Um, no. Even if you’ve just lost your job, there’s something fundamentally churlish about blaming the very phenomenon that’s elevated you above the subsistence level since the day you were born. If the world owes you compensation for enduring the downside of trade, what do you owe the world for enjoying the upside?
Dani Rodrik likely wants to remind us again of the Stopler-Samuelson theorem. And Paul Krugman might add:
What all this comes down to is that it’s no longer safe to assert, as we could a dozen years ago, that the effects of trade on income distribution in wealthy countries are fairly minor. There’s now a good case that they are quite big, and getting bigger.This doesn’t mean that I’m endorsing protectionism. It does mean that free-traders need better answers to the anxieties of those who are likely to end up on the losing side from globalisation.
Update: Dani also weighs in.
