That's true, but no rational economist or politician believes that tariffs are here to stay. They're a reflection of Trump's ideas rather than a recognized modern economic policy. Even then, Trump's goal was to combat China's policies, not create a long term system of import and export taxes to protect American workers.
As a result, there hasn't been significant industrial investment in the US. That's one of the problems we've had with Covid: the PPE, medications, and ventilators are all manufactured overseas. We've had to retool our auto manufacturers to spin up ventilator production. You'd be crazy to invest in US manufacturing since the tariffs look about as permanent as a White House press secretary. You know you'll be undercut and put out of business in just a few years.
