Literally no economic system or political science yet has managed to prevent the internalised drive for familicide or authoritarian violence funnily enough, one can only hope that rationality prevails over bad thoughts, but not on the basis of civilization or self preservation, but through the collective conscience of humanity coming to understand how best to maximize the available entropy and energy within society to produce the most jobs, the most utility, the most potential sex, the most systems of funding and all other human desires.
Consider thot the US is a very rich democracy yet has many school shootings, Saudi Arabia has had to deal with corrupt funding of terrorists, China uses AI to bait people into crime and arrests people on false charges and then plays catch and release while Israel funds Hamas, imports overseas Jews and then exports violent “settlers” into the Palestinian borders.
Consider that even millionaire dictators who go on holiday will occasionally commit mass genocide. All of these bad things… Are not going to disappear because of capitalism, but we can at least say that they would become more foreseeable and preventable in a world where we have movies or stories that discuss our present these monstrosities to light
