Donald Trump never said he wants to build a “wall” at the US/Mexico border. He said Wal-Mart! It’s a unique new economic model where each facility will have doors for workers on the Mexican side of the border, and doors for customers on the US side. In a direct one-to-one relationship each US citizen will have a Mexican national to manufacture all the cheap junk they buy. You’ll actually know the name of your underpaid industrial slave.
It’s a win-win situation: the workers get jobs so they want to stay on the Mexican side, and US companies get huge breaks on their labor costs so they’ll want to stay on the US side. And did I mention the people on the Mexican side will want to stay on the Mexican side? So that’s like a win-win-win situation.
