I like Sweden, if I could and weren't lazy to learn their language, I would emigrate to live in Sweden.
Dunno much about Finland, except it has a lot of lakes. Always picturing it as place with never ending winter. Also Nokia is going down.
Norway is cool too, but from what I know they are relying on oil, much like Libya was before the war. I'm not sure what they'll do in 50 years.
To me, it seems that only Sweden has healthy economy which won't fall apart in next few centuries. Similar to Germany but not as rich.
