Except, more likely, there are few available competitors to the tarriffed product and now the consumer covers the increased cost. Meanwhile, local alternatives, where they are available, price up because, well they had market when the pre-tarrif import was available and their own delta was what it was, so they can push the price up to just capture more profit with the same or still larger market, depending on the good.

The point is that deploying the sort of policy is incredibly tricky in the best of circumstances, and still likely to do more harm than help. And that you think, of all people, someone as very obviously stupid as Trump is capable of threading that needle is beyond baffling.
