Yes that’s the idea. For example John Deere or Cat, they make in the USA and export to other countries with a tariff on it to help another country “ compete”. However the net negative is if Deere and cat use imported steel instead of US steel. That’s just a snap shot.That is an excellent objection. In short, tariffs are the tool the US is using to 'balance trade'. The stated intent is to get others to lower their tariffs on us; leverage removal of bans against our products, negotiate purchase of more US products, and (as they said) leverage changes in labor practices.
US companies manufacturing in the United States with materials sourced domestically will feel little of these waves. It’s where I’m putting my money.
