It's definitely a huge shift, but I think most would agree that the waning of the idea of American exceptionalism comes down to life in the rest of the world getting better, not life in the US getting worse. The rest of the modern world spent half the past century coming back from the brink after two world wars that left American lands almost entirely untouched. The US had a head start with modern innovation and prosperity but the rest of the world has caught up. Who cares about which arbitrarily defined nation state is "best"? It'sbecoming a great time to be alive in places all over the world, and that's a good thing. I don't think America is the greatest country in the world, but I don't think any other country truly deserves that title either. It's kind of an antiquated concept really, given how interconnected and global everything has become.
