If we are going to survive, we are going to need to adopt at least one more currency, one that parishes with resources and wares, and encourages spending and recirculation through the local economy, rather than being sucked out of the community by some distant central banking system, which is what is happening with our current currency. We need the balance of multiple currencies, lest we fall into a corporate funded plague of individuals with no community.
Quoting Life Inc.: How the World Became a Corporation and How to Take it Back by Douglas Rushkoff, page 171:
"To this day, the bias of centralized currency is toward scarcity and hoarding. This slows down the rate at which money circulates, while concentrating wealth at the top. Instead of encouraging cooperation and community, it promotes competition and individuality."
