This is extremely non-scientific, but I am an american living outside of the us - and I often wonder 'what's wrong with us' when I meet Americans. Maybe we just have it too easy, maybe we don't have to open up our minds to other cultures (we are the dominant one). But I've met enough people that just make me think c'mon man! That said, we're the dominant culture for a reason - we have some super talented people. At the end of the day, 'flouride' probably isn't the root-cause of our 'unique'-ness.
