Capitalism brooks no competition. You won’t find another economic system to study that isn’t markedly worse.
Look into what the Blackfoot Indians were doing. Their lifestyle inspired Maslow’s Hierarchy of Needs — though he gets it pretty wrong IMO.
But here’s the thing: the Blackfoot didn’t really have an economic system divorced from other systems. It was all part of a whole that valued people and made sure everyone had what they needed.
Now here’s the kicker: Its my belief their society was based on spreading abundance. Whereas Capitalism is based on spreading scarcity.
OK, so there's capitalism, socialism, communism can't really exist, and then the Blackfoot Indians..?
