The entire logic of human existence can be formulated in five words — ‘produce in order to consume.’ Our reason and sense of justice revolt at the notion of a man who should perpetually consume without producing anything. Everybody understands that children should consume on credit: it is right that old persons should end by consuming what they have produced in their prime; it is perfectly proper that the worker should rest when tired, and consume a part of his surplus products. But he among us who should voluntarily live On another’s labour, and share useful things without adding to them, would be a true parasite.
