A LOT of that came from received culture growing up in California as a boy in the 1990's. I no longer want to be at the top of a pile of monkeys. I want my daily labor to support others in my community (broadly) rather than working to enrich a few people who will own everything and control our economy.
I think if you grow up in a society that tells everyone "greed is good" then you're going to think being greedy is human nature, but actually anthropologists know that societies have again and again existed based on mutual support of one another. I am simply suggesting we drop this "greed is good" mantra and focus on helping one another. And I think it can be more economically efficient when you value each person's life more or less equally.
