The question was for a specific example, not some moral vague strawman.

The question is a good one, right to the heart of the claim. Without specific examples, especially ones that are not post selected (i.e., pick all tariffs at a point in time and see of that was beneficial), it is silly to claim tariffs are useful when there is ample evidence of when they cause significant harm to the economy.

So, have a case for a timepoint where the set of tariffs ended up being demonstrably beneficial for an economy?
