sorry to say but all the 'all cultures have pluses and minuses' crap doesn't cut it for me.
i'd much prefer a culture than celebrates individuality , enterprise and freedom of speech and expression (the US) than a culture which is collective oriented, honour oriented and tells people to bite their lips on just about everything (most of asia).
But it cuts it for me. It's not about what you prefer or don't prefer...it's that no culture is absolutely perfect (what is perfection anyway). There's always something that could be improved. I'm not saying I'd rather live in Pakistani culture but it has its good parts too.
Frankly, when you say that U.S culture is the best (encompassing the whole country, not the different nuances of separate areas)...that's just laughable and you merely come across as disillusioned.
