And if you were serious about it, you'd realize that there are some jobs that will not be done by Americans for various reasons (salaries to make really cheap shit).
So instead we should be working with the countries south of the border to take up that slack instead of demonizing them. We could move a helluva lot of the supply chain for a lot of stuff to the Americas if we had somebody who understands supply chains, but unfortunately, he's busy running Apple.
But just imagine if we moved a lot of stuff back to the US, Canada, and Mexico and points south - the actual supply chain would be extremely short - railroads and ships wouldn't be crossing oceans, and if a lot was moved to railroads, the whole "just in time" thing would not be subjected to shitty conditions in the Pacific. We could even get Rick Perry's fabled Trans-Texas Corridor going, linking South America and Mexico all the way through Canada (and Buccees would have franchises at every exit).
But no.
