@chr honestly, a lot of what we like to call "human nature" or "greed" is part of social conditioning. we are in a society where we're told to look out for ourselves, taught that life is some big competition to amass capital or at the very least stay afloat. we have ingrained in us a sense of artificial scarcity thanks to how our society operates.
if we radically changed society and waited a generation or two, i believe this would change.
