Quite frankly, Power, in itself, is sort of an overrated concept. People in society strive and train in order to gain wealth and strength, whether through connection or hard work, those in power control those below them.
A system like that is bound to crumble but yet it persists. Why, you ask ? Because power is dynamic.
It changes with time and those in power will continue to be replaced by stronger and wealthier individuals. It simply means that it is possible to grasp this sort of power for ourselves.
It's not an easy thing though, people strive to obtain it but merely crumble to dust under the pressure. However, a small percentage of society with determination and a little helping hand at times, can obtain that power.
