The fact that labour is external to the worker, i.e., it does not belong to his intrinsic nature; that in his work, therefore he does not affirm himself but denies himself, does not feel content but unhappy, does not develop freely his physical and mental energy but mortifies his body and his mind. The worker therefore only feels himself outside his work, and in his work feels outside himself.
Karl MarxAll our inventions have endowed material forces with intellectual life, and degraded human life into a material force.
Karl MarxMoney is the alienated essence of man's work and existence; this essence dominates him and he worships it.
