The worker always has the right to leave his employer, but has he the means to do so? And if he does quit him, is it in order to lead a free existence, in which he will have no master but himself? No, he does it in order to sell himself to another employer. He is driven to it by the same hunger which forced him to sell himself to the first employer. Thus the worker’s liberty, so much exalted by the economists, jurists, and bourgeois republicans, is only a theoretical freedom, lacking any means for its possible realization, and consequently it is only a fictitious liberty, an utter falsehood.
– Mikhail Bakunin, ‘The Capitalist System’
