Quite an interesting talk:http://www.audioanarchy.org/antiwork/04-In_Praise_Of_Idleness.mp3
(The title of the talk is hyperbolic. Really, he means that moderation in work should be praised. He's not advocating idleness, which is the root of many vices.)
He said that in 19th century England, 15 hours was the average time people worked per week! He also makes an interesting point that a leisurely working class threatens the wealthy class, although he doesn't think it should, nor does say there shouldn't be an aristocratic class.
