So clearly you’ve not read the book, which I mean fair enough but then at least try to understand what the argument is before disagreeing with it based on dogma. Here’s how it defines a bullshit job:

Final Working Definition: a bullshit job is a form of paid employment that is so completely pointless, unnecessary, or pernicious that even the employee cannot justify its existence even though, as part of the conditions of employment, the employee feels obliged to pretend that this is not the case.

The idea being that the person actually doing the work is in the best position to tell if their work actually means something.

this concept that some jobs are ‘real’ and others are ‘fake’ is just class-confirmation bias that has no basis in economic reality.

Good assertion, I hope you’re ready to defend it against…

Gerte: In 2010 I worked as a receptionist at a Dutch publishing company. The phone rang maybe once a day, so I was given a couple of other tasks:

• Keep candy dish full of mints. (Mints were supplied by someone else at the company; I just had to take a handful out of a drawer next to the candy dish and put them in the candy dish.)

• Once a week, I would go to a conference room and wind a grandfather clock. (I found this task stressful, actually, because they told me that if I forgot or waited too long, all of the weights would fall, and I would be left with the onerous task of grandfather clock repair.)

• The task that took the most time was managing another receptionist’s Avon sales.

The book is full of exciting testimonies like this. Which is to say, the assumption that bullshit jobs don’t exist is clearly false.

but the truth is people generally value the investment banker far more than the teacher and the 1000x pay is reflective of that, especially as the teacher doesn’t help them increase their own wealth.

Investment bankers actually wouldn’t fit the definition in thr book anyway, but also hell no? Plenty of people want there to be more teachers in the world, or at least would consider that to ve a good thing out of hand. I struggle to think anyone ever thought the world needs more investment bankers. Besides, education is the best investment an average person can make by a long shot.

this idea some there is some perfect world where you don’t have to pretend to care about nonsense to advance your career is delusional

Just world fallacy. Just because something is normal doesn’t make it not bullshit, but also clearly a farmer or factory worker’s career doesn’t inherently involve pretending to care about nonsense. You should really read the book, if only to disagree with it in a more educated manner.
