Make no mistake, there have been negative consequences from global trade and our dependence upon foreign trade. There have been positive ones too, which is to say, war/conflict is less appealing for both sides.
Additionally, the pain you are talking about is permanent pain. The US till not be able to replace Chinese labor cost effectively, no matter what. Your cheap plastics that cost $10 will cost $16 almost overnight. In the even that opens a big enough windows for companies to be incentivized to risk building up the capacity to make the items domestically, you run into labor supply constraints. Unemployment is LOW, so this would cause wages to rise, further reinforcing a high cost of living and damping domestic production. Combine that with the promised reduction in immigration, you are compounding the effect. Finally, this domestic capacity is being articially propped up by tariffs means they have no external market. People think Americans inherently make things better and somehow planting the seeds for a manufacturing restoration will make us competitive globally. That simply not how it works. We will simply be making higher priced, similar quality cheap goods, with a higher amount of regulation to contend with, and at a smaller scale than other countries. So ultimately this whole protectionist bubbles we are building is completely inorganic and not sustainable.
There are better ways than blunt tarriffs. It's just nothing can or will stop the globe from being a competitive place. Americans have this no fantasy we can exist in isolation with the same amount of success as we did while trading with China. It's just not possible.
I will say that I think the deals we make with certain countries are exploitative towards the US. China's outright theft of American IP is real. We can fight that in targeted manner(e.g. restricting the sale/trade of emerging tech) while still trading openly with them with things that have no future being made here. Additionally, I'd much rather we rely on Mexico and Latin American countries for cheap labor and trade than China or Vietnam. I just think the fantasy of domestic mfg renaissance justifying huge tarrifs(especially across the board with friendly countries), alongside economic sacrifice, is problematic. Additionally, the general voting populace will not allow it to continue to for long when prices go up and up. So it would be abandoned in 4 years but cause long term damage for nothing.
