In addition there now exists an incredible imbalance between the governments military power and the populations man power. Throughout history there has always been an imbalance however, up until recent times, man power was enough to overthrow or overcome most armies as armies are usually comprised of a minority of the population rather then the majority. This is still true in many undeveloped countries where revolution takes place frequently because the imbalance is not too large and actual problems exist. In the USA for example, this is different. Basic needs for survival are satisfied and the government only infringes on what we have establish as our freedoms. Additionally the US government controls a military so powerful that few other nations or armies on earth can realistically compete with it (setting aside nuclear power). Thus it does not make any sense how man power could over come this obstacle. This again discourages revolt or revolution. The only way to overcome this obstacle is to appeal to the soldiers empathy as human beings. This is a knifes edge though. It requires quite a lot of death to appeal to a soldiers empathy. Too much though, and they become desensitized and cant be stopped.
The next issue is that a revolutionary population has not existed in the developed world for quite some time. This is unlike populations in eastern europe, africa, asia, or the middle east where many generations were the children of former revolutionaries. The last successful revolution in the USA was the end of segregation. The spirit that existed then has all but died out. The revolutionary spirit now exists in two kinds of people. #1 Establish intellectuals such as Christopher Hitchens, Richard Dawkins, etc. The issue is that although they make fantastic orators and writers they fail to take actual action themselves despite their incredible power due to fame. Instead they spend their efforts pleading with the world to do that job in their stead because they care to greatly for their own self preservation and lively hoods. They mostly appeal to the second kind of people who actually do take action albeit incorrectly. These are the young adults who want to bring about revolution. They can be anything from anarchists to modern communists. Their issue is firstly that they are far too divided. Unlike with segregation there isn't any clear goal or method to bring about that change. There isn't any united purpose. As a result there is a serious lacking of direction in the revolutionary population.
The next issue is the ridiculous obsession with freedom and power of the people which leads to the notion that a revolution should be without a leader. This was the failure of the Occupy wall street movement. Despite the warnings and urgings of Slavoj Zizek who actually appeared at the protest, the protestors failed to and actually refused to put forward a leader to represent their cause. This was because of their obsession with not having leaders, their inability to cohere on their plans or structure a plan, and their inability to create a reasonable
