To be fair US is extremely rich in other natural resources other than oil. It is not the richest country in the world because Americans are such misers. Norways oil money could go to some Exxon or such and regular Norwegian could live in poverty.

OK, so the US' sovereign wealth fund would be 5-6x less per capita than Norway's, so less effective, but nonetheless capable of benefitting Americans substantially.

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.
