They want to remain in control and never be displaced.
You can tell when a country is either totalitarian or when it's heading that way when they begin seeking increased control over the media, when your communications are subject to routine governmental monitoring, when you can become criminally suspect for having cash, when they're afraid of you being able to encrypt anything because it might be Terror/ChildPorn (read as "forming plots against them"), etc.
Most of all, they don't want to end up dead like Saddam and Qaddafi.
They have valid fears of that becoming reality. Just like other politicians....
