That is not what the user above you said.

They're explicitly pointing out that the US (and most of the western world) has abandoned the manufacturing sector of their economy, outsourcing work that used to employ millions of people to the developing world.

This is a trade-off that can benefit both countries, but, it is wise to consider both WHO benefits from this, and what the LONG-TERM implications of this entails. It's great for an investor class in America that has the capital to create factories in China, and it's great for China to take USD and start to employ their workforce. But, the question is whether or not this is actually a good thing for the American worker.

The rust-belt would certainly have an opinion on this. My father was a factory worker that was able to support a family on a single income, and when that manufacturing plant closed, it absolutely destroyed the finances of my family.

Yes, but I'm pretty sure he doesn't know that and thinks flapping between protectionism and TACO is a brilliant strategy for achieving the best of both worlds rather than an idiotic strategy guaranteed to result in the worst of both worlds.

"Destroy American affluence so that we can't pay with assets instead of exports" is probably the worst conceivable way to unwind the exorbitant privilege of the American Economy. We could have spent that money helping people, instead we spent it on wars and tax breaks for billionaires. We could have spent that money on targeted industrial policy (the IRA and CHIPS acts under Biden were examples of this done right, just not at the scale we needed) but instead we are doing it the hard way. Sigh.
