History teaches us that central authorities dislike escape routes, at least for the majority, and are therefore prone to closing them, so that control of a limited money supply can remain in the hands of the very few. In the 1930s, gold was the escape route, so gold was confiscated. As Alan Greenspan wrote in 1966:

As momentum builds in the developing deflationary spiral, we are seeing increasingly desperate measures to keep the global credit ponzi scheme from its inevitable conclusion. Credit bubbles are dynamic — they must grow continually or implode — hence they require ever more money to be lent into existence.
