I do tend to agree with the comment about "people who are power hungry seek positions of power." No matter what system you have you're going to have positions of leadership that have to exert some form of "power" over others and the worst people of any society are going to gravitate to those positions.

Well yes. That’s just natural. But I imagine it can minimized when you have a society that doesn’t promote being parasites and screwing over other people as part of the national dream.
