Can we agree that so far humanity has not manage to create an anti-fragile governing system? We engineer ever more complex governing systems, but humans keep figuring out ways to corrupt them. I cannot envision a system that would be anti-fragile, hence the need for periodic resets. Even my local council ruling over a village of a couple of thousand souls has been embroiled in corruption scandals.
Going back to the original topic, I don’t think it is the priority of the electorate to change the system. First they want to change the people in charge, which is a per-requisite to changing the system anyway.
Actually the whole of left-wing ideologies is based on the concept of fighting human hierarchies i.e. it literally predisposes the existence of an elite class. Capitalism/Socialism is only a subset of that. I’m not sure how you can be a human adult (?) with and kind of lived experience and claim that it all boils down to the economic system. Have you never interacted with other humans irl?
