It's the inability to see the forest for the trees. We were raised in a capitalist economic system, as were all of our past family members. The failings of capitalism appear to be the failings of human nature. In reality, meta analysis of multiple studies on human greed show that people will be inherently more kind to each other than be cruel. Quick search will bring up many articles on these studies. Plus, exchanges in material goods within communities where money hadn't been invented would show that people didn't barter, they gave their goods away to their neighbors, and the good deed would be remembered and reciprocated in times of need. You can look up "Gift Economy" in Wikipedia.

I also highly recommend reading or listening to the audiobook for The Dawn of Everything A New History of Humanity by David Graeber and David Wingrow. It is extremely interesting and eye opening.
