It is clear, that when the rate of interest is increased, the gains of money-lenders are augmented, and the money gained will buy a greater quantity of property and labor.

The increased gains of the lender must be paid by the borrowers, by the productions of their own or of others' labor.
So Adam Smith, speaking of "the Origin and Use of Money" (_Wealth of Nations_, p.

33), says: In order to avoid the inconveniency of such situations, every prudent man in every period of society, after the first establishment of the divisions of labor, must naturally have endeavored to manage his affairs in such a manner as to have at all times by him, besides the peculiar produce of his own industry, a certain quantity of some one commodity or other, such as he imagined few people would be likely to refuse in exchange for the produce of their industry.
Labor is the one paramount force which develops the resources of the world.

It produces all the wealth; it pays, in the last analysis, all the taxes--National, State and municipal; it produces the wealth which sustains all the institutions of learning, as well as ministers to the profligate luxuries of the idlers and sharpers who add nothing to the wealth of society, but on the contrary constantly take from it, and who have not inaptly been termed by Dr.Howard Crosby the "dangerous classes;" it makes the wealth which gives a few men millions of dollars as their share, either as rental or usurious interest upon capital invested in the production of wealth; and it creates the vast surplus which lies in the coffers of the Federal and State treasuries of our land.
The producing agency, without which there could be no wealth; without which the landlord could exact no rent and capital could draw no interest, the producing agency alone receives an inadequate proportion of the wealth it produces.

The man who conducts any business requiring labor and capital not only exacts an unjust proportion of the laborer's hire, but takes more than he justly should as interest upon his capital and as reward for his own time and labor, often amounting to no trouble or labor, he delegating to other hands, such as foremen or overseers, the absolute control of his investment.
