I can’t outright refute the claim that work, even of the menial type, provides some sense of purpose and gratifies a deep need for duty.
Even when I’ve been writing an album and focusing on personal hobbies, and even when I despise my workplace and my megalomaniacal manager I can’t deny that it provides me with a strange sense of duty and purpose that I can’t seem to derive from anything from anything that doesn’t involve some deadlines, directives and doing things I don’t really enjoy.
I wish it weren’t true but I think it’s evolutionarily engrained more than a mere social construction.
I certainly wouldn’t mind never working again or only volunteering my time and efforts, but I do feel that there would be a small part of me which furtively desires duty and discipline, which would be left unfulfilled.
