We've already had a political revolution. That's what the Right did when they dug up Friedman and waved him around like a decomposing scarecrow, and funded any number of think tanks to do the evangelial work needed to sell his reform message.

It was a very quiet revolution, but effective because - as Techno says - the Keynesians had weaknesses. In the middle of an energy crisis it was easy to throw out the Keynesian message and replace it with monetarist crankiness.

Now we've had twenty years of crank economics flopping around incontinently in the mainstream, with the inevitable hilarious results.
