I thought of that scenario myself, but then discarded the idea. That would entail undoing a whole litany of regulations, taxes, labor laws, and and high wages. Add to that the fact that all of the companies that offshored are now entrenched in those countries, the earliest having moved there over two decades ago.
Even if Trump could remove all of the barriers mentioned, I highly doubt these companies would come back to the US.
Anything Trump can do, the next President can un-do.
