They don’t even necessarily have positive benefits for manufacturers unless they somehow have a supply chain that exists only in the US all the way down. The automakers are against tariffs, for example.

This may kill more manufacturing than it creates.

That's why you implement them reciprocally, to force anyone else implementing them to reduce theirs. Their problem is that the method they used to identify the tariff levels was, generously, crude. And also that it was implemented too sharply.

However, as a political tactic, the sharp implementation gives them breathing room to re-calibrate before the midterms. That comes at a real GDP cost, though.

I find it interesting that you are downvoted and yet nobody have a reason why you're wrong. Even the answer you get seems to agree with you.

I feel like that's not true (really, zero positives? never? that would mean a whole lot of people is patently stupid), but I'd like to base my opinions on facts, not feelings.
