What the protests and demonstrations do promote is awareness, however. One of the main reasons this disparity is able to continue unchecked is because people are ignorant to it. They may feel it when they walk through a rich neighborhood and see how people in their own city are living so much more lavishly than themselves, but they do not always contribute it to powerful corporations and the global financial system as a whole. Therefore the protests raise awareness of the problem to those affected by the problem. It points a finger. This is all well and good.
Those who are unaffected by the problem are those people on top. They are already aware of it because they are there to ensure that this hierarchy remains in place. They are also the only ones with the power to change the system. Many of them try, but the majority of them have no qualms with being at the top of the proverbial food chain.
The only way to affect real change is to infiltrate the system of power. One must do this through education, social climbing, and hard work. To overhaul the power system you have to become a part of it and bring it down from the inside, replacing those people in power who are consumed by greed and corruption and enacting a new social order. This is called revolution.
The Occupy Movement is a good first step, but without follow-up action it is simply an empty gesture. It will only serve to aggravate the middle and lower classes into criminal activity, thereby widening the divide between the rich and the poor, which will in turn proliferate the problem. The only way to be successful is to complete the revolution of the power wheel.
