From the article:
Karl Marx noted, “But in its blind unrestrainable passion, its wear-wolf hunger for surplus labour, capital oversteps not only the moral, but even the merely physical maximum bounds of the working-day. It usurps the time for growth, development and healthy maintenance of the body. It steals the time required for the consumption of fresh air and sunlight…. All that concerns it is simply and solely the maximum of labour-power that can be rendered fluent in a working-day. It attains this end by shortening the extent of the labourer’s life, as a greedy farmer snatches increased produce from the soil by reducing it of its fertility” (Capital, Chapter 10).
