That's a good observation about the British. They're also really pessimistic (Americans are broadly positive). And, unfortunately, they're very small minded (polar opposite of Americans). That's the result of being a fallen Empire, I guess.

I like the Dutch: they're stubborn and everyone has an opinion on everything BUT they respect that. Heck, it's expected. That's something they have in common with Americans (very direct and opinionated). They have a similar background (America was colonized by various Christian sects, The Netherlands was the central hub of lots of sects because it was the only place they managed to live together without killing each other). Yet they're pragmatic, and largely class-less. Same as the Scandinavians. They also share the same 19th century ideas over work as the Yanks (>40h weeks, retire at 67), only they have holidays. Protestant work ethic at work.

BTW, I would recommend spending some time living in a foreign country - as a native (INTEGRATING, not moving to Spain to live with a load of rich British ex-pats) to anyone reading. It really opens your mind, and changes the way you think about yourself (and the world as a whole). Even better if you can combine it with learning another language.
