There's a difference between what I would selfishly like, and what is the best model. Of course I'd like to work for 30hrs a week, but thats a pipe dream, because most probably productivity would go down.

Also, the countries with the least working hours per week in the OECD are the Netherlands, Norway, Denmark, Germany, Switzerland. (https://stats.oecd.org/Index.aspx?DataSetCode=ANHRS)
Not exactly countries where you'd say that productivity was low.
