La imaginación al poder

If the Treasury were to fill old bottles with bank notes, bury them at suitable depths in disused coal mines which are then filled up to the surface with town rubbish, and leave it to private enterprise on well tried principles of laisser-faire to dig the notes up again... there need be no more unemployment and with the help of the repercussions, the real income of the community would probably become a good deal larger than it is. It could, indeed, be more sensible to build houses and the like; but if there are practical difficulties in the way of doing this, the above would be better than nothing.

John Maynard Keynes
The General Theory of Employment Interest and Money
