I get why people think that every job but theirs is fake. There's a sense that we sort of intuit that in complex orgs the actual load-bearing positions differ from the org chart (cf. Ed B's post about Peggy and the University). BS jobs flatters the, "only I do real work" impulse.
I thought Graeber (RIP) made a pretty good case. I had a bullshit job of one sort or another for much of my career, and if he'd asked me, I'd've said so.
Exactly. So much of the discourse seems to be trying to argue with people that no, their job actually *is* valuable! Personally, I've never had a job I would consider to be entirely bullshit, but I generally trust people when they say theirs is one.
