Norway puts all its oil money into a national trust it uses to improve the quality of life for its citizens like provide free education. The US government says its illegal to cancel student debt.
Sure, but the US starts and supports a lot more wars than any other country and wastes as many tax dollars on it as the next ten countries combined, so it's fair to single them out.
Basically all wars start (and end) out of economic interests (which come in a wide variety, eg land, easier enforced economic policies over another country, colonialism with military bases, or even just pain old money spent on war industry).

I would dispute this very strongly, unless you simplify 'economic interests' to mean anything and everything that brings gain to anyone, at which case a politician starting a war solely for PR to stay in power would count as doing so for 'economic interests'.
True, but even politicians can't start a war without incentivizing a whole machine of people to do it. And that power needs to come from somewhere and kept being fed.
The victor never really (or voluntary) leaves the spoils, or the land.
It is not all that bad. Wealth creation needs peace, rule of law and happy to spend consumers. I would be more afraid some ideological guy leading country towards what his ideology says it must be.
