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 get mad about my companies org chart and pay structure not reflecting the actual load bearing positions that is not the same as thinking I am a load bearing position or that managers are useless.
Having held a combination of managerial and analytical/technical roles (often at the same time) over several decades, I tend to think the analytical jobs are "easier". There's little appreciation for what mgmt deals with, the breadth of skills it takes, the time commitment, and the pure energy drain
