Just wrapping up a several weeks trip to Europe (London, Cologne, Edinburgh) as we speak. I think I'm having the opposite observation. Western cultures have so much in common it has actually been surprising to me. I always expected to be amazed by the differences, but if you throw out all of the superficial stuff the set of appreciable differences is rather smaller. As for his specific points 1. I have no idea how so…
I wonder if more Americans would travel through Europe if they knew how easy it is. EVERYBODY speaks English. And yet, you still get to experience the cultures and augment your worldview a bit.
What you get is a not a first hand view, but a 2nd hand view, from the worst observer possibe.
Im pretty sure, that language is key to any culture. And because of that Americans, even when they travel, will have less understanding of the culture, than the natives have of the states, simply because we can actually read your constitution, watch your daily show, know your founders and the culture that shspes your idenity.
Want to learn about the world? Dont travel! Learn a language.
