The reason power corrupts is simple: when your actions are amplified, it's very easy to think that your opinions are more important than other people's lives -- because, in effect, they are. The fundamental problem, is the existence of systems that allow such amplification -- it's obviously immoral, promoting destruction and murder as a matter of policy.
Since every fantasy is destructive, they must be eliminated from government.
Instead, government should simply help things that already exist -- things that people have invested their labor in.
But this must be done in an equitable fashion. Powerful people should not have more access to government than any other person. Only in this way, will government be transformed from a power-wielding monstrosity, to something collective, which genuinely nurtures the world it is part of.
