The system won’t be taken down because there are not enough citizens that want it taken down. Most Americans are so dumbed down that they think the gravy train will always be there for them.

Look at the Presidential candidates now running. There is not a leader of men among them. The vast majority of citizens have lost faith in the things that made this country great, and they are sitting on their hands.
