There is a certain powerlessness to youth. The older generation contain finances, experience, and a high tolerance for the dispicable nature of humanity. We also fail to acknowledge that it takes skill to live to an old age. If they have white hair, then they know how to survive. 

Do not be disheartened. For idealisms is the source of change and it lives with the youth. What true change has on it's side is and always will be is time. Do not underestimate the strength and virtue of patience. Many things can be taken from you. But you are the agent of change. The weilder of time. 

Fight until they hear you or until they run out of the thing they cannot take from us.
