К вопросу о нефтедолларах:

The answer lies in a remarkable decision taken many years ago to ringfence the flood of oil revenues from the North Sea. Every dollar earned is swept straight into what was once called the State Petroleum Fund but is now called the Government Pension Fund. The truth is that Norwegians are simply not spending their oil windfall, but putting it aside for the future. What's more, none of the money is allowed to be invested in Norway.

The fund has ballooned in size and recently became the world's biggest pension fund, for the first time outstripping "Calpers" the $200bn Californian Public Employees fund.

Так что к благосостоянию норвежцев эти деньги имеют отношение примерно такое же, как вклад в пенсионную кассу - к зарплате.
