So if a normal work week is counted at 40 hours, and there are 99 hours of leisure according to that chart for a modern man with a degree, then it works out that the average person on that plot line is now working 168 - 99 = 69 hours on average or 69 / 40 = 172.5% of a normal week. Sounds unbalanced to me.

Juliet Schor has an excellent book on this subject The Overworked American: The Unexpected Decline Of Leisure http://www.amazon.com/Overworked-American-Unexpected-Decline...
