As an American I think it's pretty badass that something like 8 or 9 of the top 10 most valuable companies in the world are all American. I'm not sure if that means we're doing something right, but it's still pretty cool for a moment.
(Not that the largest 4 companies are tech companies, so that explains part of it...)
