I don't think people should be obligated to work 65 hours a week, because everyone wants to have free time which can spend witch his/her family. Spending a lot of time at work is connected with worse physical shape and worse contact with members of family. This second thing might be cause of divorces or growing up children without one parent. Especially people working long hours in offices don't want to do sport after coming back home. They usually watch TV or work on computer and later they have problems with their health.
