Soybean farmers in Iowa are less susceptible to Chinese tariffs because China moved a significant number of their imports to Brazil in the last Trump administration. Those sales aren't coming back soon, tariffs or no tariffs.
Trump is essentially enacting an import substitution program. But that requires long-term capital investment, which requires economic stability and foreign investment. The way to approach this are programs like Biden's CHIPS act, which he's walked away from. It also requires a highly trained work force, but our government is underinvesting to reverse the academic decline of the past decade and we are making it harder for foreign workers (and students) to bridge the gap.
All of this inhibits economic growth. Most of our fiscal and societal problems depend on economic growth to fix. The damage done in the last week can't be offset by the nickels and dimes that DOGE is saving - our interest payments on the debt will increase, we will have fewer inflows into social security, our tax revenues are declining and we are spending less on mitigation programs for disease and natural disasters.
Essentially, we looked at Brexit, sighed, and gasped a little too confidently, "Hold my beer!"
