Our actors, our screenplays/stories, our comedians, our dollar being trading at 9 cents better, how - in terms of tourism - people of other countries receive us better than Americans, how Toronto, Vancouver and Montreal are now more "hip" than New York (my hipster friends tell me this one - they say New York and LA are too mainstream now or some ****), how our school systems are better, how our healthcare is better, how we're more rich in natural resources, how we're geographically larger...
-or perhaps it's because no matter how much we brag about our more lofty attributes, we'll always be the USA's *****.
