Norway does not prove that at all.
Norway has almost no industry other than oil. If oil shut down tomorrow their sovereign fund could keep the country running for about 10 years.
10 years isn't really long enough to transition to other industries. It's barely long enough to educate the next generation in new technology.
(Source: Norway's imports per capita were $16.9k, and its fund is $195K per capita.)
Norway is hoping that oil will shut down slowly, giving them time to transition, using the fund as a cushion. But historically industries tend to shut down "slowly, then all at once".
Edit: I didn't see you wrote "work without the corruption". My reply is misdirected, my reply is about the economy. In regards to corruption I agree with you.
