Companies seeking lowest cost moved factories to another country and now that total costs there are higher, move jobs back to the US. However, US workers are no longer available because massive job cuts forced them to seek other lines of work. Ultimately, the jobs will not return to the US because the ecosystem has been destroyed. The other country will then be free to raise prices since it owns the means of production. See TVs, washing machines, refrigerators, etc... US workers then either innovate, find entrenched industries, or go into low wage service work. Pundits then try to improve the lot of the next generation with better education.
