Karl Marx: Consequently, labour-power is a commodity which its possessor, the wage-worker, sells to the capitalist. Why does he sell it? It is in order to live. But the putting of labour-power into action – i.e., the work – is the active expression of the labourer's own life. And this life activity he sells to another person in order to secure the necessary means of life. His life-activity, therefore, is but a means of securing his own existence. He works that he may keep alive. He does not count the labour itself as a part of his life; it is rather a sacrifice of his life. It is a commodity that he has auctioned off to another. https://wordsmith.social/protestation/quotes#quote9165
