"Debts are subject to the laws of mathematics rather than physics. Unlike wealth, which is subject to the laws of thermodynamics, debts do not rot with old age and are not consumed in the process of living. On the contrary, they grow at so much per cent per annum, by the well-known mathematical laws of simple and compound interest ... It is this underlying confusion between wealth and debt which has made such a tragedy of the scientific era."

They find out that 'Fractional Reserve' Banking leads to an inflating money supply, moreover one plagued by cycles of boom and bust due to its elasticity. They dislike this - they want money to work as a safe store of value by fixing its total supply. The Gold Standard is one way of doing this.
