> What they stopped manufacturing was menial and low-end product

This statement is as inaccurate as the comment you’re trying to debunk. The fact is that China leveraged it’s low-end manufacturing work to work its way up the chain and now is the leader in many areas: https://itif.org/publications/2025/09/23/how-china-is-outper.... E.g. China has been investing heavily in radar technology and as a result has air to air missiles with comparable range to the U.S. https://en.defence-ua.com/weapon_and_tech/why_the_us_is_alar...

There are synergies to having the high end stuff and the low end stuff in the same place. The story of IBM developing System 360 mentions the benefit from the ladies who wound the wire core memory and the guys who designed the computer on the same campus in New York. We gave that up when we outsourced the “menial” stuff abroad.
