Conspiracy theories: can a family control the world?

People love conspiracy theories and some are even studying conspiracy theories seriously and publishing relevant books about conspiracy theories. However, can any of conspiracy stories be true? There is one story that fascinates many conspiracy lovers: a secret family or a secret society controls the entire world. I do not believe in any conspiracy theories, and I want to solve why it is impossible for a secret family or a secret society to control the entire world.

If hypothetically speaking there was such a secret family or a secret society having such power of controlling the entire world, the society or the family would have incredible amounts of money and power. To control their money and power, they would have to make connection with others and create their money and power networking. Their networking would not help to make them secret. However, if they did not create such networking, they would be at the danger of losing power, as the networking would help them to secure their power. Because the modern community is built based on teamwork, the information would be eventually leaked to the outside world, then the secret family or society would no longer be secret.

Moreover, controlling the entire world is a very complicated job. When dealing with such complicated job, there must be enormous uncertainties. If any uncertain state went wrong, the secret family or society would fail to control the world or keep it secret. It is impossible to ensure any uncertain state always goes in the right direction, so it is impossible to have a secret family or society that is able to control the entire world.

Overall, it is just logically impossible to have a secret family or society that controls the world.
