Slavery and Slack is a book by Joseph Winogrond. It being published chapter by chapter by C.A.L. Press in their journal Modern Slavery, the Libertarian Critique of Civilization.
Here is a brief excerpt that I found particularly interesting.
As a society and a culture we are mired in an unreasonable fear of slack. art and education are the activities of leisure, and in a perfect world they would serve only leisure. Our professed representatives of leisure – our artists, writers and teachers, – will begin their real work only when everyone has slack.
Until then they serve two purposes: They are either entertainers for the rich or they are the polite police of the slackless poor. Perhaps this is why, as our social slack has continued to decrease over the past century, our schools, prisons and employment buildings have begun to look so much alike. A blueprint for lifetime warehousing is widely accepted by a people who have forgotten what real leisure is like.
