" Cannot the labourers understand that by over-working themselves they exhaust their own strength and that of their progeny, that they are used up and long before their time come to be incapable of any work at all, that absorbed and brutalized by this single vice they are no longer men but pieces of men, that they kill within themselves all beautiful faculties, to leave nothing alive and flourishing except the furious madness for work. "

― Paul Lafargue , The Right to Be Lazy
