Of the Interest of Money and its Causes Just as the prices of things are fixed in the altercations of the market by the quantity of things offered for sale in proportion to the quantity of money offered for them, or, what comes to the same thing, by the proportionate number of sellers and buyers, so in the same way the interest of money in a state is settled by the proportionate number of lenders and borrowers.
Though money passes for a pledge in exchange it does not multiply itself or beget an interest in simple circulation. The needs of man seem to have introduced the usage of interest. A man who lends his money on good security or on mortgage runs at least the risk of the ill will of the borrower, or of expenses, lawsuits and losses. But when he lends without security he runs the risk of losing everything. For this reason needy men must in the beginning have tempted lenders by the bait of a profit. And this profit must have been proportionate to the needs of the borrowers and the fear and avarice of the lenders. This seems to me the origin of interest. But its constant usage in states seems based upon the profits which the Undertakers can make out of it.
The land naturally produces, aided by human labour, 4, 10, 20, 50, 100, 150 times the amount of corn sown upon it, according to the fertility of the soil and the industry of the inhabitants.
It multiplies fruits and cattle. The farmer who conducts the working of it has generally two thirds of the produce, one third pays his expenses and upkeep, the other remains for the profit of his enterprise.
If the farmer have enough capital to carry on his enterprise, if he have the needful tools horses for ploughing, cattle to make the land he will take for himself after paying all expense of the produce of his farm. But if a competent labourer who lives from day to day on his wages and has no capital, can find some one willing to lend him land or money buy some, he will be able to give the lender all the third rent, or third part of the produce of a farm of which he will become the farmer or Undertaker. However he will think his position improved since he will find in the second rent and will become master instead man.
If by great economy and pinching himself somewhat of his necessities he can gradually accumulate some little capital, he will have every year less to borrow, and will at last arrive at keeping the whole of his third rent.
If this new Undertaker finds means to buy corn or cattle on credit, to be paid off at a long date when he can make money by the sale of his farm produce, he will gladly pay more than the market price for ready money. The result will be the same as if he borrowed cash to buy corn for ready money, paying as interest the difference between the cash price and the price payable at a future date. But whether he borrow cash or goods there must be enough left to him for upkeep or he will become bankrupt. The risk of this is the reason why he will be required to pay 20 or 30 per cent profit or interest on the amount of money or value of the produce or merchandise lent to him.
Again, a master hatter who has capital to carry on his manufacture of hats, either to rent a house, buy beaver, wool, dye, etc. or to pay for the subsistence of his workmen every week, ought not only to find his upkeep in this enterprise, but also a profit like that of the farmer who has his third part for himself. This upkeep and the profit should come from the sale of the hats whose price ought to cover not only the materials but also the upkeep of the hatter and his workmen and also the profit in question.
But a capable journeyman hatter with no capital may undertake the same manufacture by borrowing money and materials and abandoning the profit to anybody who is willing to lend him the money or entrust him with the beaver, wool, etc. for which he will pay only some time later when he has sold his hats. If when his bills are due the lender requires his capital back, or if the wool merchant and other lenders will not grant him further credit he must give up his business, in which case he may prefer to go bankrupt. But if he is prudent and industrious he may be able to prove to his creditors that he has in cash or in hats about the value of what he has borrowed and they will probably choose to continue to give him credit and he satisfied for the present with their interest or profit. In this way he will carry on and will perhaps gradually save some capital by retrenching a little upon his necessities. With the aid of this he will have every year less to borrow, and when he has collected a capital sufficient to conduct his manufacture, which will always be proportionable to his sales, the profit will remain to him entirely and he will grow rich if he does not increase his expenditure.
It is well to observe that the upkeep of such a manufacturer is small compared with the sums he borrows in his trade or with the materials entrusted to him, and therefore the lenders run no great risk of losing their capital if he is respectable and hard working: but as it is quite possible that he is not so the lenders always require from him a profit or interest of 20 to 30 per cent of the value of their loan. Even then only those who have a good opinion of him will trust him.
The same inductions may be made with regard to all the masters, artisans, manufacturers and other Undertakers in the state who carry on enterprises in which the capital considerably carry on enterprises in which the capital considerably exceeds the value of their annual upkeep.
But if a water-carrier in Paris sets up as the Undertaker of his own work, all the capital he needs will be the price of two buckets which he can buy for an ounce of silver and then all his gains are profit. If by his labour he gains 50 ounces of silver a year, the amount of his capital or borrowing will be to that of his profit as 1 to 50. That is he will gain 5000 per cent while the hatter will gain only 50 per cent and will also have to pay 20 or 30 per cent to the lender.
