Well, who's going to move all the existing tooling to factory sites in Mexico then? Where are they even going to find good factory sites in Mexico with access to good transportation (ports and rails) and skilled labor force on such short notice?
Moving manufacturing is a major undertaking for any company, of course, I don't expect someone like Jim Kramer to know that.
Of course, but the thing is, it's been decades since NAFTA, and all the good sites for manufacturing has all been taken by someone already. So, if they try to move now, not only will they have to build the factory, they'll have to also build power stations/railways/port expansions, which could take multiple years.
