For a relatively angry-toned comment, I feel you hit the nail on the head.
From an economic perspective, however, there can be no revival of American manufacturing, because there has been no collapse. Because of automation, there are far fewer jobs in factories. But the value of stuff made in America reached a record high in the first quarter of 2016, even after adjusting for inflation. The present moment, in other words, is the most productive in the nation’s history.
If the bottom falls out, the US may find that there are no customers for their comparative luxury goods and no US citizen willing to work for little enough to be competitive with anything else.
I am, of course, an random guy on the internet and my observations are worth slightly less than that, so who knows ;-)
