How to fix this? The way to fix it, Summers says, is to charge people for saving money. To avoid the charges, people would spend the money, thus reducing savings to the level of investment and restoring full employment.

Summers acknowledges that the problem with his solution is that people would take their money out of banks and hoard it in cash holdings. In other words, the cash form of money provides consumers with a freedom to save that holds down consumption and prevents full employment.

Summers has a fix for this: eliminate the freedom by imposing a cashless society where the only money is electronic. As electronic money cannot be hoarded except in bank deposits, penalties can be imposed that force unproductive savings into consumption
