Put those monkeys underwater and you might conclude that drowning is in their nature. I know of the studies you’re referencing regarding monkeys being taught to use money and I’m aware that they were done with monkeys in captivity. In the same vein, the debunked study about “alpha” wolves was done on wolves in captivity and observations of wolves in their natural environment countered the study’s findings. Our actions are a result of the context and material conditions that we are in.

People dominate others for personal gain because they live in a system that rewards them for doing so. Place those people in a system that rewards them for helping others and the very same selfish impulse will make them saints. The “tragedy of the commons” is enlightenment era defeatist bullshit. The commons existed and were managed by people for thousands of years before capitalists enclosed them and dared to claim that it was the inevitable result of human nature.
