...humans need purpose even if it is something as simple as a methodical job.
I disagree with this. I do not believe that a methodical. mundane job provides that for people. Most people detest what they do which only adds to the stress and pressures they feel. When you factor in the physical (and perhaps mental) ailments that people suffer from, it becomes clear that people are not getting much out positive of a job other than a check. Yet, they are getting a host of negative issues from it.
