It gets harder and harder for them to maintain control with large populations. The Ponzi scheme starts to break down so rather than relinquish control, they “rebalance the budget” by eliminating large chunks of society. I remember reading an essay about how all the major wars tracked identically with economic depressions. And how it’s no mistake that wars used to be fought by lining everyone up (maximize the death toll, make everyone an easy target, and take their debts off the books). Sick assholes. There’s more than enough room on this planet if they just cut us loose).
