They are spending the money. On factories, machines, infrastructure, oil, other commodities and new buildings. Most of which are NOT in the USA.
How are we all going to be rich if we don't have high paying jobs? What high paying jobs will we have if everything of value is made elsewhere.
All the people saying "Pat is an idiot" are dodging the question completely. OK, we heard you!!! You don't like Pat! Great. He's not my top choice for a golf partner.
But I don't see real answers to the questions he poses. NAFTA was not passed with Al Gore aruguing "by passing this the Mexican economy will collapse, the south western USA will be overrun by illegals, and millions of high paying jobs will leave America never to return".
Did he? NO!
And what do those people do with the money? They spend it. Eventually, someone's going to buy some American stuff with the money. Otherwise, they'll be left holding a bunch of worthless green paper.
