Professor Laughlin, of Harvard, in his work on Political Economy (page 72), says:
It is quite evident that the name dollar does not always have the same value, although people often think it does. We get into the habit of using names without thinking what they really mean. The 23.22 grains in a gold dollar may be exchanged sometimes for more, sometimes for less, of other commodities. When it is exchanged for less, its value has fallen relatively to all other commodities, and, even if the name dollar remains the same, its value has fallen. One must then offer more dollars than before for the same commodities. That is, when money falls in value, prices rise; when money rises in value, prices fall.
Now, we shall say a few words in regard to another function, a means of paying long contracts, or debts which run over a long term of years.
Suppose that I loaned you in 1880, $1,000 for twenty years. In that year the $1,000 bought a certain quantity of corn, wheat, sugar, salt, wood, hats, and shoes. In 1900, when you are to pay me back the $1,000 in money, if prices have changed, you may give me back the same amount of money, but you will not return to me the same purchasing power over other things. If for some reason prices have fallen between 1880 and 1900, it will take less money to buy the same quantity as before of corn, wheat, etc. If so, the $1,000 you return me in 1900 will be of more value than the $1,000 I gave you, and it would be unjust to oblige you to give me more than you borrowed. If, on the other hand, prices have risen, then the $1,000 in money would buy me less than before, so that I should lose. * * * Hence, the value of money (gold or silver) does not remain the same for any length of time; and the precious metals, while they are very satisfactory for exchanges which do not take very long to complete, can not serve as a proper measure of value during a long term or years.
Ricardo, the greatest authority on the gold standard, the financial writer, more highly regarded throughout the world than any other that has ever appeared in Great Britain, whose logical utterances have never failed to attract the attention of mankind, stated the true condition of things in 1810, and advocated the true policy for Great Britain.
In his "Proposals for an Economical and Secure Currency," Ricardo makes the following statement, which I commend to the careful attention of the advocates of the single gold standard:
While a standard is used, we are subject to only such a variation in the value of money as the standard itself is subject to; but against such variation there is no possible remedy, and late events have proved that, during periods of war, when gold and silver are used for the payment of large armies distant from home, those variations are much more considerable than has been generally allowed. This admission only proves that gold and silver are not so good a standard as they have been hitherto supposed—that they are themselves subject to greater variations than it is desirable a standard should be subject to. They are, however, the best with which we acquainted.
If any other commodity less variable could be found, it might very properly be adopted as the future standard of our money, provided it had all the other qualities which fitted it for that purpose; but while these metals are the standard the currency should conform in value to them, and whenever it does not, and the market price of bullion is above the mint price, the currency is depreciated. This proposition is unanswered and is unanswerable. Much inconvenience arises from using two metals as a standard of our money; and it has long been a disputed point whether gold or silver should by law be made the principal or sole standard of money. In favor of gold it may be said, that its greater value under a small bulk eminently qualifies for a standard in an opulent country.
And I may here remark that it requires an opulent country to maintain the single gold standard, and the country does maintain it at very great expense. I do not wonder that he thought an opulent country, a creditor country, the only one that ought to adopt it, for no other country can afford to adopt it. But, like many people who in attempting to improve their condition in society attempt luxuries and extravagances which they can not maintain and which force them back into the ranks from which they came, so nations in attempting to establish the gold standard may find themselves reduced from opulence to poverty.
Ricardo continues:
