Norway's oil wealth has protected it somewhat from the vicissitudes of funding which Sweden suffered during the 1990s. Norway was a bit like Sweden's less wealthy brother, but oil changed all of that, mostly averting the economic crisis Sweden suffered.
It looks like it is time for Norway to begin its welfare state reformation just as wealthy brother Sweden did in the recent past. This will be fun to watch. Fortunately for Norway, they have a ready made, culturally, and socially similar model to crib from.
