Uh, Switzerland, anyone? Quite a lot of culture difference in a country that has a lot more than just fiscal unity. I'd say, more than in most countries that are a lot bigger, both geographically and by population size.
Actually, here in Poland, EU slowly (too slowly) forces us to accept our own cultural diversity.
Stop panicking. If our culture was defined by our banking system then we wouldn't have that much of a culture.
Switzerland, but also US. Some Europeans tend to see U.S. as a monolith while in reality they're quite diverse - the difference between New York and Nevada is as big as between Poland and Spain.
Well, yes, I realized that soon after posting, didn't want to go back and make a post flood though.
Also, I'd be surprised if this wasn't true for every sufficiently big country. I'm almost sure it's true for China, and that's even though their government isn't exactly the most supportive of cultural differentiation.
