The tariffs are not to raise revenue - the tariffs are to have foreign countries lower or drop their tariffs on goods produced in the U.S.
These countries are buying items already and we want them to buy from us instead of Germany, France, the British Commonwealth of Nations, etc.
If you sell to us, you buy from us.
“If you sell to us, you buy from us.”
To Trump’s people it is not so simple. They expect that if we buy $X amount of goods and aservices from a country, that country needs to be buying the same amount of goods and services from us, even if they have no tariffs on any imports from us. In some cases that makes no economic sense on either side of the exchange. There are countries we buy from because that country has the best of something (bananas?) compared to most other places, and so we buy from them because it makes econonic sense. But their standards of living is so far below them we have little to offer that they can afford - so we have a trade decifict with them, so Trump is slapoing them with tariffs. Tariffs will not slow the imports from them nor cause them to buy Boeing jets or Ford autos from us - they can’t afford them.
