“
So you think that money is the root of all evil? …Have you ever asked what is the root of money? Money is a tool of exchange, which can’t exist unless there are goods produced and men able to produce them. Money is the material shape of the principle that men who wish to deal with one another must deal by trade and give value for value. Money is not the tool of the moochers, who claim your product by tears, or of the looters, who take it from you by force. Money is made possible only by the men who produce. Is this what you consider evil?

When you accept money in payment for your effort, you do so only on the conviction that you will exchange it for the product of the effort of others. It is not the moochers or the looters who give value to money. Not an ocean of tears nor all the guns in the world can transform those pieces of paper in your wallet into the bread you will need to survive tomorrow. Those pieces of paper, which should have been gold, are a token of honor—your claim upon the energy of the men who produce. Your wallet is your statement of hope that somewhere in the world around you there are men who will not default on that moral principle which is the root of money. Is this what you consider evil?

Have you ever looked for the root of production? Take a look at an electric generator and dare tell yourself that it was created by the muscular effort of unthinking brutes. Try to grow a seed of wheat without the knowledge left to you by men who had to discover it for the first time. Try to obtain your food by means of nothing but physical motions—and you’ll learn that man’s mind is the root of all the goods produced and of all the wealth that has ever existed on earth.

But you say that money is made by the strong at the expense of the weak? What strength do you mean? It is not the strength of guns or muscles. Wealth is the product of man’s capacity to think. Then is money made by the man who invents a motor at the expense of those who did not invent it? Is money made by the intelligent at the expense of the fools? By the able at the expense of the incompetent? By the ambitious at the expense of the lazy? Money is made—before it can be looted or mooched—made by the effort of every honest man, each to the extent of his ability. An honest man is one who knows that he can’t consume more than he has produced.
