I think another part of the problem is who is attracted to positions of power and why they are attracted to those positions.
If someone wants power to fix things, they’ll tend to have other motivations that will conflict with the pursuit of power because they don’t intend to use that power for their own gains.
But if someone wants power to abuse it, then their personal motivations and pursuit of power line up. Not to mention how much easier it is to sell an idea when you don’t care what the truth is.
