JPMorgan Chase CEO Jamie Dimon, who oversees the country’s largest bank, said Wednesday that Americans need to “get over it” when it comes to President Donald Trump ’s tariff plans driving up prices, as many economists have warned they will.

Experts have warned that Trump’s tariffs, which he’s said could also include a 10 percent tariff on all foreign goods, could send domestic inflation through the roof and trigger trade wars abroad. For private sector leaders, the cost of doing business would likely rise—increases which would then probably be passed down to consumers, too.
