There's a book about why power seems to attract this sort of people - can't remember the name right now, might update later.

In short, it's not power on its own, but rather the systems we built around and for power, making it unattractive for people we want to end up in power, while the people who we don't want to end up in power pursue it regardless because they want power for the sake of it.

What I'm trying to say is, this is another issue that we can actually tackle and solve to a large degree. There's hope!
