@Daojoan Apparently it was generally rather egalitarian and consensus-based prior to the Holocene. The advent of lootable resources, monopoly of violence and the inability for the plebs to get out set the scene for power differences, wealth inequality and the ability to transfer that through generations.
So the small percent of sociopaths who would have been cast out of the group for the vast majority of our species' existence now have a vice like grip on all our lives.
This is not "human nature" but the result of increased hierarchisation over time. Still, the good news is that when it all collapses the plebs have historically done better*
