Even serious academic studies say that Americans are more narcissistic than people in other countries.
You are a very sick society, and no, it's not happening in every developed country. I am currently living in Portugal and Portuguese people aren't like that.
I've lived in too many countries not to know the difference between Americans and other nationals. And the research backs me up.
