The Rich Disappear
For many, the idea of becoming rich without becoming famous is the ideal situation, and this conspiracy theorist believes that there are many people who are living that life in secret. They claim that there are likely many billionaires that we have never heard of simply because those billionaires chose to disappear from normal life.

Among all conspiracies, this one is probably the most believable since there is no reason why becoming a billionaire would make you famous in the first place. In fact, the odds are that this is true. There is no reason why a wealthy person needs to advertise their success. Many probably choose to be anonymous so that they can live a peaceful life.
