Agree. Societies can start going backwards if they don't have any input. But it's not like Norway has ever been sealed off. We've gotten influence from surrounding countries, and collaborated. As the world gets smaller and closer, influence is easily achievable. I mean..today, I don't need a Japanese dude in Norway to make me sushi. I don't need germans in Norway in order to have a BMW. I don't need to travel or meet great thinkers in person to be influenced..they are on the Internet in some way or form.
Like I said, I'm not against different people or cultures. It could be a benefit, but only if they want to contribute.
