Are you sure? The impression I get in NL is that women don't particular like to work too much : they favor 32 over 40 hrs. I even overheard a young woman say she went to 24 hrs ( from 32 hrs ), because 'why not?', they could afford it.
My impression is women are less ambitious and value quality of life much more than men ( I don't blame them, I try to do as little as possible as well ).
