Former US Treasury Secretary: Trump's tariff policy goes against economic logic

Former Treasury Secretary Larry Summers said in an interview that Trump's tariffs defy economic logic, meaning higher prices for consumers and much higher input costs for American producers.
Summers questioned: Why among so many countries in the world are we now deciding to wage an economic war against Canada? Canada has a higher minimum wage, a higher base wage, and more worker protections from unions than the United States. I just don't understand the logic of these policies. There is no doubt that this is a regressive tax on American consumers. (Jin Ten)
