"Taking the second half of the [20th] century as a whole, even allowing for the longer holidays won by the European workers, the reduction in the hours performed annually by a worker varies from almost nothing to, say, 30 percent. During the same period production, depending on the country, climbed by 400 to 500 percent. The contrast is instructive. Free time, though indispensible to allow people to develop their personality, is not an important item for our society, which is more preoccupied with the commercialization of the limited leisure time available." -- Daniel Singer, Whose Millennium? Theirs or Ours?
