[I have utilised, mainly in the first chapter and in parts of the second and third, the material, much revised and re-written, of some articles which were published during 1922 in the Reconstruction Supplements of the _Manchester Guardian Commercial_.--J. M. K.] CHAPTER I THE CONSEQUENCES TO SOCIETY OF CHANGES IN THE VALUE OF MONEY Money is only important for what it will procure. Thus a change in the monetary unit, which is uniform in its operation and affects all transactions equally, has no consequences. If, by a change in the established standard of value, a man received and owned twice as much money as he did before in payment for all rights and for all efforts, and if he also paid out twice as much money for all acquisitions and for all satisfactions, he would be wholly unaffected. It follows, therefore, that a change in the value of money, that is to say in the level of prices, is important to Society only in so far as its incidence is unequal. Such changes have produced in the past, and are producing now, the vastest social consequences, because, as we all know, when the value of money changes, it does _not_ change equally for all persons or for all purposes. A man’s receipts and his outgoings are not all modified in one uniform proportion. Thus a change in prices and rewards, as measured in money, generally affects different classes unequally, transfers wealth from one to another, bestows affluence here and embarrassment there, and redistributes Fortune’s favours so as to frustrate design and disappoint expectation. The fluctuations in the value of money since 1914 have been on a scale so great as to constitute, with all that they involve, one of the most significant events in the economic history of the modern world. The fluctuation of the standard, whether gold, silver, or paper, has not only been of unprecedented violence, but has been visited on a society of which the economic organisation is more dependent than that of any earlier epoch on the assumption that the standard of value would be moderately stable. During the Napoleonic Wars and the period immediately succeeding them the extreme fluctuation of English prices within a single year was 22 per cent; and the highest price level reached during the first quarter of the nineteenth century, which we used to reckon the most disturbed period of our currency history, was less than double the lowest and with an interval of thirteen years. Compare with this the extraordinary movements of the past nine years. To recall the reader’s mind to the exact facts, I refer him to the table on the next page.
