Not what I was going for but I can see how it can be read that way. My point was that librarian is a job that requires a lot of academic training because it’s a job that heavily relies being able to navigate academic work, which really isn’t the case for plumbing or other trade jobs. That doesn’t make the work mindless, you obviously have to engage your mind to engage in any skilled work. It’s just a different kind of mental engagement, I don’t think anyone who has worked a ‘traditional’ academic job and a trade job would contest that.
