evidence: Sen. J.D. Vance defended former President Donald Trump’s tariff policy, saying it penalizes importers who undercut American workers, including with "slave labor," not consumers. [...] When asked whether he acknowledges that tariffs cost consumers money, he said "no, I don’t," arguing that making imports more expensive has a "dynamic" effect by encouraging producers to make their goods instead in the U.S. and avoid the tariffs. "I think economists really disagree about the effects of tariffs. Because there can be a dynamic effect, right? So what some economists will say is what you just said, that it will actually raise costs for consumers. But what other people say, and I think the record supports this other view, is that it causes this dynamic effect where more jobs come into the country," he said.
