Tariffs like he is proposing have never been implemented at the scale he is proposing unless you go WAY back to like the early 1900’s and 1800’s when this was the United States main source of income. Taxes on people were far less. No state or income taxes because most of the income came from these tariffs. Now do that, and keep the taxes we have now? Now you have a problem
Trump already proposed an option to remove the federal income tax and use tariff money in place of it. Will the others, even with a Republican controlled Congress pass it? No.
I think people are failing to realize that even with a Trump presidency and a chance of full Congressional control, the swamp and for life politicians will still work against him. Mitch McConnel, I'm looking at you.
