Trade Works. Tariffs Don't. The administration’s new tariffs threaten to spark a global trade war. 'China, the EU, Mexico and Canada have already retaliated or announced plans to retaliate with billions of dollars in tariffs on American-made products. Tariffs imposed by the United States are nothing more than a tax increase on American consumers and businesses–including manufacturers, farmers, and technology companies–who will all pay more for commonly used products and materials. Retaliatory tariffs imposed by other countries on U.S. exports will make American-made goods more expensive, resulting in lost sales and ultimately lost jobs here at home. This is the wrong approach, and it threatens to derail our nation’s recent economic resurgence.' Tariffs are the Wrong Approach | U.S. Chamber of Commerce So now major U.S. corporations (like GM) AND the U.S. Chamber Of Commerce are stating the obvious....tariffs/trade wars DO NOT WORK.
