I would generally agree on the idea that “corruption” isn’t really real, and that bad outcomes from poor or malicious leadership are the result of systemic failures, not individuals not being good enough.
I would, however, disagree with the notion that the problem is that people who break the rules of a system will inevitably win against those upholding the rules of the system. I reject the notion that there are real rules that can be broken, there may be a set of rules written down that people are told to fallow or else but that is not what is actually influencing people’s decisions, at least not directly. Instead there is a set of incentives and perceptions, If a set of perceptions and incentives create a bad outcome, then those are what need to be changed.
Simply eliminating these systems that allow for concentration of power won’t solve the issue ether, as new systems will come into existence that will fill the power vacuum left behind.
