The economist has a piece about how much American kids study (http://www.economist.com/world/unitedstates/displayStory.cfm?story_id=13825184&source=most_recommended) that starts with the requisite clichés about the lazy French.
Did you know that the French are the fifth most productive people of the OCDE, before the US and way before Japan?
It's true that the American work on average 11% more than the French but did you know that on average the French work more (and better) than the German?
Interestingly, there seems to be an inverse correlation between hours worked and productivity: the less you work, the better you work.
