Well, tariffs done in Trump's way (depending on which way we're talking about, as he had quite a few different ways during his campaign, and is pretty honest about not giving a shit about what he says in campaigns, and tells everyone that he's not promised a single thing) would cause lots of problems.
Musk even said it.
"Elon Musk, Trump allies say his tariff plans could cause short-term pain for consumers"
"Top allies and surrogates of former President
Donald Trump, including
Tesla CEO
Elon Musk, are agreeing with economists who say Trump’s economic
policy plans would raise prices for consumers, but Trump’s allies contend the effect would be short-term and would be worth it in the long run."
What is "short term" exactly? Trump doesn't give a damn about getting reelected now. "Short term" could be 12 years.
