I think the problem that doesn't get stated enough, is that reshoring is necessary for national security. We can't build practically any military hardware, and the majority of civil use hardware, without foreign materials. If we get in a war with China, we can't rebuild or maintain anything that gets lost or damaged. Heck, we can't even make enough artillery shells to keep up with Ukrainian demand, let alone refill our war stocks, and that doesn't include Patriot missiles, THAAD missiles, etc. Even for the manufacturing we do have, we have offshored the processing of raw materials of things like aluminum, lead, and in many cases steel. This has been somewhat constraining (see COVID shutdowns) for our low rate manufacturing, but if we get in a shooting war with an adversary that has any kind of offensive capability, and our stuff starts getting shot down, sunk, blown up, or shot, we can't replace it faster than it can be consumed. Thus, we run out of bullets, missiles, shells, planes, tanks, ships, torpedoes, etc. We need capacity to process and build products from mining to use, or else our military and economy are at the whims of foreign countries. We didn't have this problem 30-40 years ago.
If tariffs and reducing regulations helps this capability, and there is financial pain (which there will be), then so be it. The fast $5 crowd of the 80s through now have screwed us over so they could make a quick buck, and its going to take years to dig us out of the hole we've been put in. Hopefully some short term pain, and massive investment to start bringing production back can kick off this process quickly, without everyone crying because their $1200 Chinese product now costs $1400.
