i think it's fine - if the context of "work 90 hours a week" is in the context of "for yourself, in the immediate proximity of your family". working to improve the productive assets of your kin is based, and people don't sweat laboring a dozen hours daily when they and their young can see the immediate benefits of that labor. those surrounding them appreciate it more and are inclined to benefit the labor also. industrialization has wrought horrors upon the human organism from which we likely will not recover.
