With respect, the idea that we are motivated to do anything only to accumulate material wealth is an insult to the very concept of sentient life. We strive for things because we have consciousness, awareness and intelligence. Life without the incessant need for accumulation to survive might afford us the chance take a less destructive path as individuals and as a species.
Communist societies were statist hierarchies where power was concentrated in the hands of the few. That particular implementation of what was called communism is not the only one possible but more a perversion of socialism designed to legitimise and reinforce certain power structures. basically human history 101 with whatever 'ism' you want to insert there.
I do think there is an ‘instinct’ to acquire or hoard more. That’s not to say that people can’t override that, but it’s there.
And it can just be a desire to be better, do more, be the best.
And I think for some people who build their own company, it’s just that. It’s not wealth or power for many (although it is for some).
As for the destructive path as a species? It’s common in nature, end product inhibition, over predation leading to population crash...
We are nothing if not animals
