So much for that side of the question. Now, let us look at another side of the question which is sometimes lost sight of. A man invents a machine: as I have shown you, it is as much the product of other men's brains as of his own. It is really a social product. He gets a patent upon the machine for a certain number of years, and that patent gives him the right to say to the world "No one can use this machine unless he pays me a royalty." He does not use the machine himself and keep what he can make in competition with others' means of production. If no one chooses to use his machine, then, no matter how good a thing it may be, he gets nothing from his invention. So that even the inventor is no exception to my statement that no man ever gets rich by his own labor. The inventor is not the real inventor of the machine: he only carries on the work which others began thousands of years ago. He takes the results of other people's inventive genius and adds his quota. But he claims the whole. And when he has done his work and added his contribution to the age-long development of mechanical modes of production, he must depend again upon society, upon the labor of others. To return to the question of abstinence: I would not attempt to deny that some men have saved part of their income and by investing it secured the beginnings of great fortunes. I know that is so. But the fortunes came out of the labor of other people. Somebody had to produce the wealth, that is quite evident. And if the person who got it was not that somebody, the producer, it is as clear as noonday that the producer must have produced something he did not get. No, my friend, the notion that profits are the reward of abstinence and thrift is stupid in the extreme. The people who enjoy the profit-incomes of the world, are, with few exceptions, people who have not been either abstemious or thrifty. But perhaps you will say that, while this may be true of the people who to-day are getting enormous incomes from rent, interest or profit, we must go further back; that we must go back to the beginning of things when their fathers or their grandfathers began by investing their savings. To that I have no objection whatever, provided only that you are willing to go back, not merely to the beginning of the individual fortune, but to the beginning of the system. If your grandfather, or great-grandfather, had been what is termed a thrifty and industrious man, working hard, living poor, working his wife and little ones in one long grind, all in order to save money to invest in business, you might now be a rich man; that is, supposing you were heir to their possessions.
