Many of the greatest economic evils of our time are the fruits of risk, uncertainty, and ignorance. - John Maynard Keynes

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.

The power of taxation by currency depreciation is one which has been inherent in the State since Rome discovered it. The creation of legal-tender has been and is a Government’s ultimate reserve; and no State or Government is likely to decree its own bankruptcy or its own downfall, so long as this instrument still lies at hand unused.
Besides this, […] the benefits of a depreciating currency are not restricted to the Government. Farmers and debtors and all persons liable to pay fixed money dues share in the advantage. As now in the persons of business men, so also in former ages these classes constituted the active and constructive elements in the economic scheme. Those secular changes, therefore, which in the past have depreciated money, assisted the new men and emancipated them from the dead hand; they benefited new wealth at the expense of old, and armed enterprise against accumulation.

The difficulty lies not so much in developing new ideas as in escaping the old ones.
