What's notable about Norway is that back in 1968, as the country was first becoming aware of its oil wealth through the newly-realised North Sea deposits (shared with the UK), the country had the foresight to tap the advice of an Iraqi ex-pat who advised the country to invest its oil funds for national growth, infrasturcture, and sustainability, and not squander it in corruption and gratuitous expenditures as so many other countries had and would.
