Trying to change the system means joining the system. If the system is set up to keep you out (as it has been and is in many cases) then how do you join it? If an outside force pushes the issue and your let in then your now running in a wheel within wheel and your output torque is nigh on nothing. Yes change can be affected but so too can change happen under a dictatorial rule because humans do not obey rules... ever. Though the change is not supposed to happen, nor allowed to happen, it will still happen.
