The prisoner's dilemma is an elaboration of the tragedy of the commons where individuals will compete with each other if they are unable to communicate their needs with each other. Both were used to prove that capitalism is the best way to allocate resources, but they ignored the fact that competition would only begin once the commons was enclosed and the working class was unable to effectively organize itself. It became a tactic of control which required the appearance that those in control share the same interests as those who are controlled.
