Extortion
If somebody gets robbed, it is much easier for the person that got robbed to try and get that person back. As the levels of organization get higher, it becomes for difficult for that person to get back against a group, gang, cartel, department, agency, corporation, government, or system. If the system itself robs a person, especially if it is a system that the person lives within it, the options available are much harder to utilize. Normally, those that live within a system and get robbed will rely on the system itself to correct that, but if the system is what robbed them, than one must go against the entire system itself in order to correct the error.
Within the Truman Show, it is the entire system that participates in the brainwashing and propaganda that robs us of the truth. Without honesty, there is no order. There are only sweet lies and money covering up the corruption that has already been established. To go against a corrupt system is far more difficult than going against any single human or gang, but it is possible and it has been done many times before.
