Not quite: bullshit jobs are when the workers themselves say their own job isn't doing anything useful. And apparently they comprise a sizeable portion of all workforce.
Of course, jobs people say are useless, jobs the workers themselves say are useless, and actually useless jobs, are 3 different sets. But I think we can confidently say something is wrong when so many workers say their own job is useless, even if they aren't: working a job you think is useless just isn't healthy.
Americans in particular always have pretty narcissistic ideas about what their jobs should be. You can see this from all the examples of hippies trying to start communes, which then fail because everyone appoints themselves official poet instead of farmworker.
Yeah, I'm gonna need a citation for that one.
Even a more thought out form doesn't do anything class analysis didn't already do.
