Economist Steven Landsburg argues:
Bullying and protectionism have a lot in common. They both use force (either directly or through the power of the law) to enrich someone else at your involuntary expense. If you’re forced to pay $20 an hour to an American for goods you could have bought from a Mexican for $5 an hour, you’re being extorted.
This is in the context of a provocative article suggesting that we should not compensate those who lose from free trade. As he puts it:
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?
