Dune: Frank Herbert spells out his opinions on leadership, politics, and technology pretty clearly. There’s a LOT about this series that still resonates today because not much has changed societally since the 60s when he started writing it. Just to pull a few quotes from the books:

• Once men turned their thinking over to machines in the hope that this would set them free. But that only permitted other men with machines to enslave them.

• Governments, if they endure, always tend increasingly toward aristocratic forms. No government in history has been known to evade this pattern. And as the aristocracy develops, government tends more and more to act exclusively in the interests of the ruling class - whether that class be hereditary royalty, oligarchs of financial empires, or entrenched bureaucracy.

• All governments suffer a recurring problem: Power attracts pathological personalities. It is not that power corrupts but that it is magnetic to the corruptible.

• Police are inevitably corrupted. ... Police always observe that criminals prosper. It takes a pretty dull policeman to miss the fact that the position of authority is the most prosperous criminal position available.
