One of the most frightening theories is one of the simplest. There is no conspiracy, there is no illuminati or small group of hidden, super rich, mega powerful leaders. Everybody is just looking out for their own, and following their own beliefs.

I think this is why so many people believe in conspiracy theories. They’re comforted by the idea that someone is in control and steering the ship, so to speak. Even if they have bad or evil intentions, at least someone is in charge.
The reality is that the world is rudderless. Even the “powerful” people can do relatively little. There’s nobody really in charge.
I’m not saying that powerful people don’t exert an enormous amount of influence or that certain groups don’t conspire in some ways to achieve ends that are less than good for mankind. All I’m saying is that, at the end of the day, they’re just people and they do the same stupid things we all do, and are subject to all our same flaws. They’re not superhuman.
