There is a mother of all recession happening soon coupled with intense effort to dedollarize. Those factories will end up abandon without recouping their original investments. I have seen how this playout. In the 60s and 50s there were doable because things are cheap and Americans have the Japanese-like ingenuity and innovation. In the 90s, Internet happened and end of cold war. In the 2000s, Chinese supplement worldwide inflations with their cheap goods and students as American human resources together with Indians. In the 2020s USA lost huge chunk of Asian human resources and facing high inflations. Americans still able to hold off due to residue economic growth from Clinton-Bush era. Coming decades they will face immense headwinds with their poorer quality of non Asian immigrants, lack of resources (oil and rare earth no where at Russia level), lack of gold (Fort Knox havnt been publicly audited for more than half century), military weak (Talebans humiliated pentagon and inpending Ukrainian defeat as American sponsored proxy state), population disparity (India+China+Russia+Asean) going to make America looks like 3rd world country population or Monaco at best. Already working in HR fields, I am seeing a lot of capable Americans execs sending their kids to Asia. Some even ditched American citizenships. You can search for extreme end of examples like Severin and Dyson. But those in the "millionaires" range make up the huge bulk of these well to do American leaving western world.
