Trump wants to cut middle-class taxes. The easiest solution? Repeal tariffs
"As the Trump administration explores ways to deliver a new middle-class tax cut, the most obvious answer is to repeal the administration’s newly imposed tariffs. Tariffs tax middle-class American families and threaten to undermine the economic growth generated from the new tax reform law".
Not even a month after signing the nation’s first major tax reform bill in more than 31 years, the Trump administration began imposing tariffs on American imports. So far this year, the administration has imposed tariffs on steel, aluminum, washing machines, and thousands of products that American businesses and consumers buy from China.
President Trump argues that these tariffs are paid by China and overseas companies, but it’s American families who bear the real cost.
These tariffs increase taxes on the middle class as they increase costs for U.S. businesses. The steel needed to produce a U.S. car is more expensive, driving up the total costs of production, for example.
