Every Norwegian - man, woman and child - is now technically a millionaire. That's right, every last one of those herring munchers is now worth a million Crowns. Now, in fairness, a hundred Krone is worth just under $18 Cdn. but that's still a chunk of cash.
The money is held in Norway's sovereign wealth fund which now stands at $828 billion US for the country of 5,096,000 citizens. The money comes from the country's North Sea oil and gas reserves and the public's decision not to squander their windfall but to set it aside for future generations. What a weird idea, eh? They save it when they could have a helluva time just pissing it all away. What's wrong with those people?
UPDATE - In response to a comment about Norway's debt, here's a 2012 chart from the IMF
Curiously enough you'll find the new, North American energy superpowers massively indebted.
