Economics and productivity
Well, there's learned helplessness, and then there's productivity.
Should the CEO of a Fortune 500 company be changing a printer ink cartridge? Heck, should his executive assistant even be bothering with that?
At some point, if the organization is large enough and the task is distinctly tech-related enough, it doesn't make economic sense to have anyone other than the "person who's paid to do it" do it. (Not that you want network engineers being called upon to perform the more menial tech tasks, but certainly a front-line helpdesk technician or other low man on the IT totem pole can be called upon to do some gofering when the situation calls for it.)
Of course, people should know how to do these basic things -- and be empowered enough to do them themselves -- if they situation warrants. But if the person makes over $100 an hour to create a marketing strategy or handle securities litigation, maybe their time is better spent than figuring out what an A0 error on the copy machine means.
