Have you considered that all countries move through phases? The US now enjoys a much higher average wage than China and most other countries. As a result, producing cheap items is always going to be tricky unless consumers are willing to pay much higher prices. Eventually China's moment will pass as their average wage increases and some other country will be the target for criticism and tariffs.
In times past the US complained about Japan because their cars were both cheaper and better. In the UK it's been everything from clothing to ceramics, replacing what were once key industries.
Trump won't manage to roll back the clock unless robots replace people in assembling phones and other tech. Just like in the UK nobody wants to pick fruit and machines are starting to take over there.
It's quite possible that this is the beginning of the end game for the US and it certainly feels like something similar in the UK. The difference I think you're observing is that Trump wants to go down fighting, taking not only his enemies with him, but pretty much everything the American constitution once valued and stood for.
Meanwhile, neither Apple or any other mass producing tech company will achieve what has been done in China .... unless they enslave their people and pay them a pittance. Hey, actually, that's an idea Trump might run with!
