World-changing economic booms are a once a nation thing, really, and depend entirely on who is in an advantageous position at the time, and particularly, who can be a source of cheap goods for the rest of the world. It was the US once because of a world war. Now it's not and it never will be again. That doesn't mean we don't make things, just that if we stop trading with the outside world out of spite, that trade merely goes elsewhere and enriches someone else. Global economics are inescapable.
