American corporations CHOSE to move their manufacturing outside the U.S. because of money. Their number crunchers advised that foreign wages would be less expensive than domestic wages to workers. Land was less expensive. Less regulation. And it cost less money to manufacture from abroad. Etc. Etc. Etc.

IF American corporations chose to repatriate their operations to American soil, their shareholders would mutiny. Unnecessary expenditures when leaving things status quo wouldn't threaten the corporation's existence. And capital. Tell me which banks would want to lend money for that purpose. Plus, all in all, if accomplished, I doubt American corporations manufacturing on home soil could make (or want to make) products that cost less than imported products that are tariffed.
