Generally Tariffs are a "tax" on goods. Can be bad as Harris inflation "tax", but not quite.
But not what Trump is talking about.
As I understand Trump's Tariffs he wants Tariffs on specific, targeted incoming items ONLY where America makes the product & makes a plethora of it well. An example would be foreign cars. Another example would be John Deere moving business to Mexico where he wants them to stay here. In other words if America makes the product well, he wants American companies to compete on an even field.
It should be noted that if American companies want to sell cars in most other countries, the other country charges a Tariff. So T's specific, targeted Tarrifs seem more fair and good for America & American companies & workers.
What wouldn't be good for anyone if Trump charges Tariffs on say Chinese production where we do not have the same product being produced here. Haven't heard of him wanting to do that, but as much as he hates China, certainly is a possibility. That would be terrible.
Broad reaching tariffs cause trade wars and are bad for everyone.....whereas there is less chance with specific targeted Tariffs.
Bottom line......huge difference between specific targeted Tariffs VS. broad ranging Tariffs. The former reasonable people should understand & be ok with.......the latter be 100% against.
