Bertrand Russell, ‘In Praise of Idleness’ In In Praise of Idleness: and Other Essays (London: George Allen and Unwin Ltd, 1935), pp. 9-29 (p. 14):

Modern technic has made it possible for leisure, within limits, to be not the prerogative of small privileged classes, but a right evenly distributed throughout the community. The morality of work is the morality of slaves, and the modern world has no need of slavery.
