It's easier to show the idiocy of the claim that tariffs won't raise prices of American products with the example of oil.
If we put a $10,000 tariff on imported autos, will you claim that US produced autos would not increase in price?
The price that the US consumer pays is irrelevant to the Free Traitor™. This has been explained to me many times by many a Free Traitor™ on Free Republic.
Free Traitor™ speak: A corporation owes its allegiance and exists only to maximize profits for it's share holders ( at least public companies). So if a tariff allows them( a domestic producer) to charge more for their product and they don't lose market share to one of it's domestic competitors and demand stays the same then a corporation benefits from the tariff. Free Traitors™ should be happy with tariffs.
