The US had a great run, because of two things. First, WWII left most of the industrialized world in shambles, and the US had it's infrastructure intact. It took years for Europe and Asia to recover. Also, most of the rest of the world was engaged in that failed experiment called "socialism" and other centrally-planned economies. We ate their lunch.
Fast forward to the end of the Cold War. Now the world starts to wake up and get that capitalism is indeed the way to go. So, now the gap between the US and the rest of the world has finally started to close a bit.
But here is the good news. The US still has the freest economy in the world, and as long as it does, we will remain dominant. It doesn't mean it's not going to be painful at times, I myself have experienced some of that pain. But Americans never backed down from competition, and they won't back down now. And we know that messing with the invisible hand always leads to disastrous results.
