We must aim at separating those services which are technically social from those which are technically individual. The most important Agenda of the S… - John Maynard Keynes

The ideas of economists and political philosophers, both when they are right and when they are wrong are more powerful than is commonly understood. Indeed, the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually slaves of some defunct economist. Madman in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler a few years back. I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas.

Like the monetarist Milton Friedman, Keynes looked to price stability as a way to shore up classical economic thinking. For the most part, he believed, laissez-faire economics worked. Supply and demand did bring society to a prosperous equilibrium. They just needed a few pieces of basic economic architecture to work: property rights, the rule of law, and price stability. But unlike Friedman, Keynes had arrived at monetarism as a creative way to expand the power of the state to fight the uncertainties and anxieties of postwar life.

If the Treasury were to fill old bottles with banknotes, bury them at suitable depths in disused coalmines which are then filled up to the surface with town rubbish, and leave it to private enterprise on well-tried principles of laissez-faire to dig the notes up again (the right to do so being obtained, of course, by tendering for leases of the note-bearing territory), there need be no more unemployment and, with the help of the repercussions, the real income of the community, and its capital wealth also, would probably become a good deal greater than it actually is. It would, indeed, be more sensible to build houses and the like; but if there are political and practical difficulties in the way of this, the above would be better than nothing.
