I think this is real to a certain extent; think of it as bureaucratic 'cruft'. However, it's also hard to spot exactly which jobs are bullshit; if it was easy, you won't have this problem of dead weight positions in big companies. There are almost certainly jobs that look bullshit but aren't, and vice versa.
