The true money standard of any country is not the material of which the money is made. The standard is not a concrete object, but a numerical relation. It is the relation between the number of units composing the monetary circulation of the country and the numbers of the population. It is the legal-tender function that constitutes money. It is the power which the law imparts to any material to pay debts and liquidate obligations. It can not for a moment be doubted that the money function, being conferred by the supreme authority, is the all-sufficient guarantee of the money value. There is no necessity for re-enforcing that value with any inferior value that may attach to the material on which the money stamp is placed. The money function is immeasurably the most important that can be conferred by society upon any material, and it is absurd to urge that that function is not of itself sufficient for the maintenance of the value of money. All the value that money can possibly have--the totality of value that can exist in the shape of money in any country--will attach to anything upon which the sovereign authority stamps it, whether the material on which the stamp is placed be gold, silver, paper, or anything else. Legislators or executive officers of the Government, by increasing or decreasing the volume of money, correspondingly decrease or increase the value of each unit of that money. For no matter how many or how few the units may be, the total value of the money of the country will be comprised within the total number of those units. A change in the number of the units effects a proportionate change in the value of each unit, and whatever the value of the unit may be, it is of the utmost importance that that value should remain undisturbed. It is absurd to maintain that a gold unit, which, as time goes on, is constantly increasing in purchasing power; is a better unit than a unit of any other material that maintains unchanging value through time. Whenever the business of the country accommodates itself to a given number of units, the only question for the Government to deal with is to maintain that value as free from disturbance as possible; and according to all authorities on political economy that can only be done by increasing or decreasing the number of units in circulation in accordance with the demands of increasing or decreasing population.
