The damage the tariffs are doing is going to be immeasurable. We are too heavily interconnected with the rest of the world at this point. And there's too much automation so we're not going to be bringing back those manufacturing jobs even if we managed to bring back the factories.
Even then, companies can't standup local manufacturing overnight and they're going to be wary of relying on tariffs for that motivation when they could be removed on a whim because someone said something nice to Trump or gave him money in some fashion -- the ways are too numerous to list -- or simply removed in 3.75 years by the next administration, which, if things keep going like this, won't be Republican...
Even now, for example, while ostensibly targeting imported autos and many imported parts, most U.S. made autos reply on a LOT of imported parts and those can't be on-shored quickly either. Trump said he doesn't care if imported auto prices go up 'cause that'll force people to buy U.S. autos. but domestic prices are certainly going to rise as well.
The Administration wants to on-shore most, if not all, manufacturing, but a LOT of things simply can't be made domestically for less, especially given wage pressures, and I imagine some can't be made here at all given other pressures, like raw materials. If he tries to push things too far, other countries may simply abandon the U.S. markets and trade among themselves.
I think the thing that bothers people most is that these tariffs don't make any sense. Punish Canada because of fentanyl crossing the border? It was like literally 47 pounds in total last year -- a suitcase full. Waiting to see when the 48.9% of voters who voted for him wake up (so to speak). :-)
