Leisure as a status symbol of the upper classes is nothing new though - it's what's required for the Good Life according to Aristotle, and it's long been the aspiration of the English upper class: a marker of nobility.<p>The famed Keynes biographer, Robert Skidelsky (The Right Honourable Lord), has an intriguing book with his son, Edward Skidelsky: <i>How Much Is Enough? Money and the Good Life</i>.<p>Starting point is an essay by Keynes from 1930, <i>Economic Possibilities for Our Grandchildren,</i> in which Keynes predicted that 100 years from then, economic progress would have improved productivity and real incomes so much that everyone (in the developed world) would only have to work 2 days a week and be free to enjoy their leisure otherwise.<p>Now, it's still a few years until 2030, but it doesn't really look like that prediction will come true - and the book is an examination on why.<p>Makes you think.
