Trump’s upcoming tariff barrage is supposed to reduce trade deficits by cutting out imports. Forgotten amid all the administration’s threats and justifications is the other side of the trade equation. More exports not only reduce deficits but also bring broader economic benefits through higher-paying jobs and greater innovation. Yet in a world of global supply chains, boosting exports means upping imports as well. Widespread tariff hikes will also hold back US-based exporters.

And unlike in most other nations, trade’s importance in the US economy has been falling in recent years.
