Earlier quoted context omitted.
> Every human being deserves an average of 8 hours of work, 8 hours of family/leisure, 8 hours of sleep and 2 days a week free.

Why, we can just make overtime and >5 in every 7 days with worked hours illegal, it's so simple...

and on whatever the Legatum Prosperity Index is: http://en.wikipedia.org/wiki/Legatum_Prosperity_Index
and Germany's OECD's Better Life Index (using the "weigh all of these equally" measure): http://www.oecdbetterlifeindex.org/#11111111111
I would argue that standard of living is higher in the US.
