That's a pretty large topic..but in short I think we always we're curious about others. I mean, we have never been totally homogeneous, like the Inuits or Indian tribes or whatever. We've always gotten influence from other countries. And even in the Viking days when we were somewhat imperialistic, a lot of vikings desired to live elsewhere. (Britain, America, Island, Baltic) But we've always been relatively homogeneous. In a society which is based on force (state ruled) I believe there must be a high degree of homogeneousness in order to obtain trust. The more liberterian the society is, the better multiculturalism works. Multiculturalism is still lower in Norway than most western european countries. We have stricter immigration laws than lets say sweden, britain, france and germany. But we are definitly seeing a lot of problems with it. The general trust in our society is decreasing, and it is now normalized to shame people who use welfare, because people are so paranoid that it's being misused or exploited.
