We are controlled by a secret organisation
I don't know whether they're called the Illuminati, they could be called anything. All I know is that they exist.
Just think about it. Consider that we humans have a hierarchy. With us at the bottom, we have no idea of what goes on at the top.
We all like wealth, most of us enjoy some manifestation of power and control. And at the top of this hierarchy, this effect would be greatly multiplied.
It just seems weird to me to think that seeing how greedy and power hungry people are, so many of us assume that no group of influential people would assemble to try to control us common people for their own benefit.
I've heard this said lots of times before - that people are likely to ignore what they don't want to see. And when somebody comes up with something that uncovers part of a secret organisation, they get shrugged off as a conspiracy theorist. It bugs me.
