Keynesians are desperate. They had an opportunity to unleash policy on the world and it failed. They are closing the hatches to their bunkers. Silver is blowing out the foxholes. The battle is almost over before it even started.
Their is no back up plan for the Keynesians. Fiat money is all they have. They will not come up with new theories, because Keynesianism has nothing to build on; it is based on make believe.
