they only know their mother tongue and normally aren't tought any second language

I'm not that sure it's all about the language. There are other countries using english as
their offical language, like england, canada and australia. But I never meet that many
people from these countries who would even think about being superior in one way or another
to others parts of the world in a way many north (some? most? )american natives seem to do.

It should be as easist for americans as for nobody else to keep themselves well informed
about the rest of the world simply *because* 90% of the relevant worldwide information
is created and broadcasted in english. Why is it then that it always occurs to me that
non-americans seem to put alot more energy in respecting other people's cultural contexts?

Ok, enough said. I'm not intending a flame war nor do I believe all US folk are like
this, so please forgive me ;) Let's get back to work.
