Someone invented a new and opaque term for a tax on imports to the country. This sort of tax has been called a tariff since at least the American Revolution, and "The Tariff" funded the federal government down until the invention of the income tax in the very early 20th century. The size of the tariff was a serious political issue from the Revolution right on.
We enacted a very stiff tariff, the Smoot Hawley tariff right after Great Depression I hit. Most historians and economists tell us that Smoot Hawley made the Great Depression worse, and prolonged it. Needless to say, "tariff" became something of a bad word most places. The exception was in union circles, the unions like tariffs.
There is a push to put in a tariff again. Only since "tariff" is now a bad word, they call it a "Border Adjustment Tax". And the newsies let them get away with it.
