President Donald Trump has long praised tariffs as key to increasing wealth in the United States, idealizing Gilded Age policies that preceded the implementation of a modern federal income tax. Among the potential benefits, Trump claims, is the ability to replace revenue from federal income taxes with money the U.S. is taking in from tariffs — a concept he has touted since his 2024 presidential campaign, most recently at a Cabinet meeting Tuesday. But tariff revenue doesn’t even come close to where it would need to be if federal income taxes were eliminated. Experts say such a plan isn’t feasible.
