I hope that this is true. We need a one world government. We must get rid of all these national barriers that do nothing but divide us and come together as it will ultimately mean that we are united.
Here is one conspiracy theory about conspiracy theories: It is those actually at the top who are promoting them.
The reason they want you to believe there is a communist Illuminati plotting for a one world government, is to make you opposed to socialism and to a one world government which are the only way to free humanity.
The reason they want you to believe that there is a global depopulation program is to get you to reproduce, you think you are "rebelling" by doing so, but you are really just helping the capitalist cause and contributing to overpopulation.
The reason they want you to believe that man-made climate change is a myth is so that you will allow them to burn fossil fuels so that they benefit from the money while the earth suffers.
The reason they want you to believe that the Jews run the world and that they are promoting race-mixing and homosexuality to destroy the white race, is in an attempt to divide us by our race, religion, sexual orientation, etc. because when we are divided, we are easier to control.
The reason they want you to believe that the moon landing is fake is so that you will deny the progress of science. In the same way that they want you to believe that GMO's and vaccines are evil, it is so that science cannot progress and will stagnate, as it is ultimately in opposition to capitalism (hence why so many scientists are socialists: Albert Einstein, Stephen Hawking, Marie Curie, Nikola Tesla, etc.)
The reason they want you to believe that the government is behind false flags (9/11, Sandy Hook, etc.), and is producing chemtrails in the air to control you, is so that you will believe that they are an omnipotent behemoth, which cannot be defeated, so that you will live in fear. When in fact, if the proletariat are united, the capitalists that enslave us would be overthrown within seconds.
I should point out that I have no evidence to prove any of this. However, it seems a perfectly viable hypothesis to me.
