> Norway has the rule of law, low corruption, people have confidence in their government, and the government looks out for the people. With or without oil, these things are tremendous assets.

I think you missed that they have tons of hydro power available which is iirc cheaper or at least on par with burning fossil fuel, so they don't even need oil. Cheap power basically runs down their hills. (Similar to how in Iceland the hot water just spawns out of the ground. Yes I'm a little jealous.)
