If you can't trade with the rest of the world your life gets hard very quickly
The major differentiator for Norway is policy, not oil quantity.
No other countries are comparable.
To be fair I think a good counterpoint is Denmark, they are doing about as well as Norway despite not having such massive amounts of oil. So surely Norway is underperforming despite the fact that they had a massive head start?
Norway won the lottery, sure they invested their winnings instead of wasting them but they are still playing on easy mode, you can count the number of countries which could have done the same with your fingers.
But how these countries use their resources is quite different.
Realistically even if they managed to accumulate a significant amount of money there would have been a lot of societal pressure to spend all of that during various economic downturns. How could a government that’s sitting on a fat pile of money ever justify cutting spending on the NHS or social services?
Except that ... it doesn't exist, because, from the beginning, we've given it all away to Big Oil, who spend some of it making sure that politicians get elected who keep supporting Big Oil.
So yes, a very fair comparison.
