Rapture was founded as a fiercely capitalist society, and look how far they got! So much progress!
In the end, capitalism is a few people on the top exploiting and brainwashing all those beneath them, and that's what ended up happening. Fontaine pretended to be fighting for the people when in reality he was using them for his own gain. Ryan used Adam to brainwash thousands of people to serve him. And in the end what did it result in? Everyone was dead or insane, the city was in ruins, and STILL they were fighting over control of the city like infants!
Jack Ryan is a great example of how capitalism treats its adherents. The entire game he was CONVINCED that he was doing what was right, what he was supposed to do, what he had chosen to do. But in reality, he was being told what to do by Fontaine, and he blindly followed, never questioning. "Atlas" treated him really kindly and convinced him that they were friends and equals, but really Jack was nothing more than a tool used by Atlas, nothing more than a pawn that happened to checkmate a king. It took complete BETRAYAL for Jack to realize he was being used! We are all being used by the wealthy of society, and so few of us realize, because the wealthy are so good at convincing us that we have it better off under capitalism.
