When you live in a rational society, where men are free to trade, you receive an incalculable bonus: the material value of your work is determined not only by your effort, but by the effort of the best productive minds who exist in the world around you.
When you work in a modern factory, you are paid, not only for your labor, but for all the productive genius which has made that factory possible: for the work of the industrialist who built it, for the work of the investor who saved the money to risk on the untried and the new, for the work of the engineer who designed the machines of which you are pushing the levers, for the work of the inventor who created the product which you spend your time on making, for the work of the scientist who discovered the laws that went into the making of that product, for the work of the philosopher who taught men how to think and whom you spend your time denouncing.
The machine, the frozen form of a living intelligence, is the power that expands the potential of your life by raising the productivity of your time. If you worked as a blacksmith in the mystics’ Middle Ages, the whole of your earning capacity would consist of an iron bar produced by your hands in days and days of effort. How many tons of rail do you produce per day if you work for Hank Rearden? Would you dare to claim that the size of your pay check was created solely by your physical labor and that those rails were the product of your muscles? The standard of living of that blacksmith is all that your muscles are worth; the rest is a gift from Hank Rearden.
In proportion to the mental energy he spent, the man who creates a new invention receives but a small percentage of his value in terms of material payment, no matter what fortune he makes, no matter what millions he earns. But the man who works as a janitor in the factory producing that invention, receives an enormous payment in proportion to the mental effort that his job requires of him. And the same is true of all men between, on all levels of ambition and ability. The man at the top of the intellectual pyramid contributes the most to all those below him, but gets nothing except his material payment, receiving no intellectual bonus from others to add to the value of his time. The man at the bottom who, left to himself, would starve in his hopeless ineptitude, contributes nothing to those above him, but receives the bonus of all of their brains. Such is the nature of the “competition” between the strong and the weak of the intellect. Such is the pattern of “exploitation” for which you have damned the strong.
