Sweden has twice the population and what? Three times the landmass?
Sweden also does not have an oil fund where it invested much of the dino profits from the last 60 years. The Norwegian one won't last forever, but I'd bet it'll last longer than any of us.
Don't get me wrong; Sweden has a decent economy and the standard of living is still amongst top-20 on the planet. Norway just struck black gold and scored higher.
