One more time; when a private central bank issues the public currency at interest, the system is a pyramid that lasts only as long as ever-larger pools of new borrowers can be found to allow the creation of new money with which to pay the interest on the old money. When new borrowers cannot be found, the pyramid collapses. When everyone in the nation (or planet) is already in debt and cannot be persuaded to borrow any more, collapse is inevitable because it is designed into the system from its inception.
Do you get it yet? The bankers designed a system that would eventually place all the wealth into their hands, but never planned what to do when they actually succeeded and society stopped operating.
And these same greedy bastard bozos want to run the world?
