If “beggar-thy-neighbor” sounds like an old phrase from a long-dead economist, that’s because it is. Adam Smith, the 18th-century thinker who also popularized the phrase “the invisible hand,” used it.

But “beggar-thy-neighbor” is a fitting label for the Trump team’s tariff fixation, as trade economist Bedassa Tadesse argues.

At its core is a familiar idea: A country can boost its own economy by punishing others. But in a world where supply chains crisscross continents, the real victims of beggar-thy-neighbor policies are often domestic industries, workers and allies caught in the crossfire.

Tadesse unpacks the Trump administration’s recent announcement of sweeping import duties – followed by a head-spinning 90-day pause on some but not all of them – and draws a line from the Smoot-Hawley Tariff Act of 1930 to the soybean standoffs of today.

Spoiler alert: History doesn’t exactly cheer this strategy on.
