If you have wondered how one can start producing, when nature requires time
paid in advance, this is the beneficent process that enables men to do it: a
successful man lends his goods to a promising beginner (or to any reputable
producer)—in exchange for the payment of interest. The payment is for the risk
he is taking: nature does not guarantee man’s success, neither on a farm nor in
a factory. If the venture fails, it means that the goods have been consumed
without a productive return, so the investor loses his money; if the venture
succeeds, the producer pays the interest out of the new goods, the profits,
which the investment enabled him to make.
