You do realize that would mean destroying every U.S. business that exports (Agriculture, Chemicals, Machining, etc.) right? U.S. exports are not minuscule, we just import a lot of oil and consumer goods. In fact, our strongest industries are the very ones that would be destroyed by an inability to export. Tariffs are never one way.
Your 100% across the board tariff will destroy major U.S. industries in return for low scale production jobs.
Much of the consumer crap that is now sold would simply go away if it weren't so relatively cheap (indeed we don't need it), so there would be no job creation.
Government Motors would lover your tariff though.
Look.
We export farm goods.
That’s pretty much it anymore. We will continue to export farm goods, because people need to eat.
A 5% tariff that escalates every year by 2% against countries that tariff us. Then the tariff is in the hands of the other countries. Just like China ties their currency to ours we tie our tariffs to theirs.
