What d.highland said is partially true. The American people will not revolt, but it's not because they are brainwashed into thinking everything is fine. People here know there is something fundamentally wrong with our system they are just too comfortable and afraid of the disruption to their lifestyle that revolution would cause. That is a legitimate fear, but that is something every revolutionary in the history of humanity has had to deal with. A revolution can only happen when the people who wish it to happen can overcome those fears.
I think another thing preventing revolution here is even though people may see something wrong with the system, no one really has any good, solid ideas on what to replace it with. This problem is compounded by the fact that no one in this nation could universally agree what the new system should be. This nation is so diverse that you would have factions ranging from Stalinists to Monarchists to Fascists. So, while I would like to see a revolution I don't see one happening until the American people can form a united front and decide what direction this country should take.
