I heard an interview with one of the GOP consultants that helped pen the Labor chapter of Project 2025(Ezra Klein interview earlier this week), and he noted that tariffs are "also revenue and a tax". He didn't fully come out and say it, but it sounds like an end around to get closer to the flat tax that GOP'ers and Libertarians want. If you tariff everything, then those who consume most or all of their paycheck for consumable goods will be effectively paying that tax.
