The economist Keynes coined the term in the 30s. He hated the stuff, and wanted governments to have a monopoly on creating fiat money.
Keynes predicted what would happen to the English economy when it went back on the Gold standard. He had no emotional concerns about gold just knew it was no longer viable as a money supply. Actually it had NEVER been viable unless permanent recession was the goal.
Thanks--it's always refreshing to encounter a hard fact that can blow speculation out of the water!
