The destructive nature of our current monetary system, according to Eisenstein, is due to that which backs it, rendering helpless everyone who deals with money, because what backs it becomes what we are, in essence, forced to worship.

Money, now an electronic notation on a computer screen, is backed by none other than growth itself — by the creation of more money.
