This is how alpha chimps function in their tribe. They resort to war and violence to prolong their rule, and it works for long enough, thats all they need for the cost-benefits to be worth it on their side.

In humanity, being the alpha chimp, you can actually just run away from the tribe with all your wealth instead of outright die and form a new identity and start a life elsewhere and change your last name and go somewhere not well known, and if you and your family does this for enough generations you are forgotten.

I think this might explain the rotten apples at the tip-top of our industrial/societal wealth classes. I think they are these people, played out over generations, having somehow survived the system that used to make it impossible to do this when at the chimp level (or even medieval maybe, maybe this new form of evasion only arose in the industrial age).
