The problem is that we're talking about "manufacturing" as one big homogeneous thing. The US obviously makes a bunch of stuff, but it has very limited ability to make lots of kinds of stuff, especially in a hostile trade environment.

The US manufacturing sector is about half the size of China's in terms of value-add, but it's much smaller by any other measure. The US has focussed on high-value verticals like aerospace and pharmaceuticals, where intellectual property provides a deep moat and secure profit margins. That kind of manufacturing doesn't produce mass employment for semi-skilled or unskilled workers, but it does create lots of skilled jobs that are very well paid by global standards.

That's entirely rational from an economic perspective, but it means that US manufacturing is wholly reliant on imports of lower-value materials and commodity parts.

A Chinese manufacturer of machine tools can buy pretty much all of their inputs domestically, because China has a really deep supply chain. They're really only dependent on imports of a handful of raw materials and leading-edge semiconductors. Their US counterparts - we're really just talking about Haas and Hurco - are assembling a bunch of Chinese-made components onto an American casting. To my knowledge, there are no US manufacturers of linear rails, ballscrews or servo motors.

If the US wants to start making that stuff, it's faced with two very hard problems. Firstly, that it'd have to essentially re-run the industrial revolution to build up the capacity to do it; secondly, that either a lot of Americans would have to be willing to work for very low wages, or lots of Americans would have to pay an awful lot more in tax to subsidise those jobs.

It's worth bearing in mind that China is busy moving in the opposite direction - they're investing massively in automation and moving up the value chain as quickly as possible. They're facing the threat of political unrest on a scale they haven't seen since 1989, because of the enormous number of highly-educated young people who are underemployed in unskilled and semi-skilled jobs.

Lots of Americans want to bring back mass manufacturing employment, but very few of them actually want to work in a factory. You can't resolve that contradiction through sheer political will.
