sure some office jobs can be worthless....in defense of my own job that sometimes feels worthless (3-5 hrs per day)....the difference to me is, IF i worked a full 8 hrs, the work performed is useful. VS a job where I believe can be fully replaced by something else. (cashier is replaced by self-checkout, cart return is replaced by aldi style coin system. landscaper is replace by new societal norms(its not required, its desired by an ever-changing beauty standard).
