Iowa farmer Bob Hemesath is concerned about Donald Trump's proposal to impose a 60% tariff on Chinese goods and a 10% tariff on all other imports, citing the potential negative impact on U.S. agriculture. Economists warn that these tariffs could push U.S. import duty rates back to 1930s-era levels, leading to inflation, a collapse in U.S.-China trade, and a significant shift in supply chains. The National Corn Growers Association and American Soybean Association have forecasted deeper U.S. crop export losses and lower domestic prices if a new China trade war breaks out. Despite these concerns, Trump's campaign suggests that a 10% universal tariff would not significantly increase prices and could stimulate economic growth and job creation.
