The aluminum and steel tariffs that President Trump is proposing will do more harm than good, affecting the US economy and American consumers negatively, holds Melvyn Krauss of USA Today. Aside from provoking a potentially devastating trade war with our business partners, a higher price on these goods would raise costs for everything related to them. Costlier metals would lead to beer and even tomatoes and paper becoming more expensive. The tariffs might result in interest rates rising faster than expected, which would hurt the stock market and weaken the economy. Trump is wrong to propose them.
