White House aide Peter Navarro said he expects President Donald Trump’s tariffs to bring in $6 trillion in revenue in the next decade, which could amount to the largest tax hike in US history.

Even when adjusting for inflation, that amount would be triple the tax increase put in place in 1942 to pay the cost of fighting World War II.

Navarro, Trump’s senior counselor for trade and manufacturing, insists it’s not a tax increase but a tax cut — echoing the Trump administration’s repeated belief that tariffs will be paid not by American consumers but by businesses in other countries or the countries themselves.

“The message is that tariffs are tax cuts, tariffs are jobs, tariffs are national security,” Navarro said on Fox News Sunday. “Tariffs are great for America. They will make America great again.”

But most economists say US-imposed tariffs are paid by American businesses and consumers in the form of higher prices on imported goods, not paid by foreigners.
