Everybody admits that the value of all other things is regulated by the play against each other of the forces of supply and demand. No reason has been or can be given why the value of the unit of money is not subject to this law. WHAT IS THE DEMAND FOR MONEY? The demand for money is equivalent to the sum of the demands for all other things whatsoever, for it is through a demand first made on money that all the wants of man are satisfied. The demand for money is instant, constant, and unceasing and is always at a maximum. If any man wants a pair of shoes, or a suit of clothes, he does not make his demand first on the shoemaker, or clothier. No man except a beggar makes a demand directly for food, clothes, or any other article. Whether it be to obtain clothing, food, or shelter--whether the simplest necessity or the greatest luxury of life--it is on money that the demand is first made. As this rule operates throughout the entire range of commodities it is manifest that the demand for money equals at least the united demands for all other things. While population remains stationary, the demand for money will remain the same. As the demand for one article becomes less, the demand for some other which shall take its place becomes greater. The demand for money therefore must ever be as pressing and urgent as the needs of man are varied, incessant, and importunate. WHAT IS THE SUPPLY OF MONEY? Such being the demand for money, what is the supply? It is the total number of units of money in circulation (actual or potential) in any country. The force of the demand for money operating against the supply is represented by the earnest, incessant struggle to obtain it. All men, in all trades and occupations, are offering either property or services for money. Each shoemaker in each locality is in competition with every other shoemaker in the same locality, each hatter is in competition with every other hatter, each clothier with every other clothier, all offering their wares for units of money. In this universal and perpetual competition for money, that number of shoemakers that can supply the demand for shoes at the smallest average price (excellence of quality being taken into account) will fix the market value of shoes in money; and conversely, will fix the value of money in shoes. So with the hatters as to hats, so with the tailors as to clothes, and so with those engaged in all other occupations as to the products respectively of their labor. NO ALTERNATIVE FOR MONEY. The transcendant importance of money, and the constant pressure of the demand for it may be realized by comparing its utility with that of any other force that contributes to human welfare.
