I mean... I think there's a couple things here... First, as I said in my comment, the man in your example is likely not working in order to "stretch [his] abilities" as was the context of my comment... Second, I'm not sure that doing something out of boredom is equivalent to a "need," regardless of how one might describe it. Third, it seems to me that many people's only source of purpose is work (partially because they must work exhaustively to survive), so, when the need or ability to work is removed, they have nothing else; the idea that "work" is either a necessity or a noble pursuit in of itself only serves to reinforce this outlook and the resulting behavior (i.e. deriving all purpose from work). I don't want to push too hard, but it should be somewhat self-evident who might benefit from a culture that perpetuates a myth of work as necessity.
