Over the course of human history, the most powerful means for increasing human prosperity — and therefore peace and happiness — is through trade. Trade is what enables people to consume more than what they can produce individually, and meet needs that they cannot meet by themselves. It’s easy to see this at work at the village or neighborhood level; it’s equally true at the global level, with even more force. When we refuse to trade with cheaper producers, we raise prices for ourselves—and, especially, for the poorest among us, who are least able to absorb the added costs. Trade creates greater good for more of our own people, and that added prosperity can help compensate and retrain people who find themselves unable to compete with the cheapest producers. Let’s keep our free trade and the wealth it creates, and use some of it in sustaining support for people who face real losses from trade.
