That leaves 28 states who are not. One of them being Alaska. Yet, at a 8th of the population Norway have. Alaska produses 400k barrels a day. or in other words, around a 7.5th of that of Norway, Norway produces around 3m barrals a day. Can we agree that their similar in size to population? If so.

GDP per capita:

Norway: $97k

Alaska: $65k

So your point being?

It's a myth that Norway is particularry wealthy only because of oil. This is not true. There are many factors which contributes to this, some of the most important ones are sound fiscal policy, spread wealth, technology building, nationalization of the energy sector, high education, stable global region, close situation to the market, predictable and stable government, sound mix between taxes and benefits, etc, etc, etc.

Although oil seperates Norway from other similar countries like Sweden, it doesn't seperate it from other similar oil producing countries at a similar population level. It is simply false to make a clear cut cause/effect relation in regards to oil.

Edit: Couldn't find any reliable religous affiliation for Alaska, so I can't to a proper comparison. But it's doubtful the oil to population comparison have little corrolation with secularization.
