Trump is right that we should try to get more immigrants from countries like Norway. It really makes perfect sense.

That's a mistaken impression.
I correspond with several people there.
Statistically, very few Scandinavians emigrate. They love their countries and are immensely proud of their values, economies, and social success.
The few who do leave usually do it for reasons of climate - seeking more warmth, and less extreme variations of daylight.
There has been a recent shift towards somewhat more right-wing policies, and the general population hates it so much that those governments will probably fall at the next election.
