Money is the route of all kinds of evil.
“The fact is that labour is external to the worker, that is, it does not belong to his intrinsic nature. 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.”
(From Estranged Labour, 1844)
“Capital is dead labour, that, vampire-like, only lives by sucking living labour, and lives the more, the more labour it sucks. The time during which the labourer works is the time during which the capitalist consumes the labour-power he has purchased of him. If the laborer consumes his disposable time for himself, he robs the capitalist.”
(From Capital, 1867)
