“If I should steal something from you, you can call a policeman and have me arrested. The law will punish the thief, and the government will return to you the stolen property, if possible, because the law forbids stealing. It says that no one has a right to take anything from you without your consent.
But your employer takes from you what you produce. The whole wealth produced by labor is taken by the capitalists and kept by them as their property.
The law says that your employer does not steal anything from you, because it is done with your consent. You have agreed to work for your boss for certain pay, he to have all that you produce. Because you consented to it, the law says that he does not steal anything from you.
But did you really consent?
When the highwayman holds his gun to your head, you turn your valuables over to him. You ‘consent’ all right, but you do so because you cannot help yourself, because you are compelled by his gun.
Are you not compelled to work for an employer? Your need compels you, just as the highwayman’s gun. You must live, and so must your wife and children. You can’t work for yourself, under the capitalist industrial system you must work for an employer. The factories, machinery, and tools belong to the employing class, so you must hire yourself out to that class in order to work and live. Whatever you work at, whoever your employer may be, it always comes to the same: you must work for him. You can’t help yourself You are compelled.
In this way the whole working class is compelled to work for the capitalist class. In this manner the workers are compelled to give up all the wealth they produce. The employers keep that wealth as their profit, while the worker gets only a wage, just enough to live on, so he can go on producing more wealth for his employer. Is that not cheating, robbery?”
