Norway's govt is not usual.... there are articles/books written about how Britain had access to even more "free money" from the North Sea oil but just lowered current taxes and spent the money as fast as it came in. Only Norway has seemed to operate with an unusual discipline to not SPEND every cent the country has ever brought in and actually save for the future.

But Norway is very homogenous and most of it's 5million inhabitants have much more in common than the typical diversity that you see in most other western countries. That allows for much more consensus on how to govern for sure.
