Fair enough. But just like every job has bullshit, every part of life has some level of bullshit. I don't think in terms of "eliminating" bullshit, but rather minimizing it.

You won't find a job that's 100% free of it. But everyone intuitively knows which ones are in the 90 to 99% range. Emergency responders, garbage collectors, transporters, powerplant employees, nurses... basically any job that's actually essential and not just something that grows another person's fortune. Once these people stop working, you notice.

So would you sign up for these jobs? Probably not, because they often require a lot of work or not much money (very region dependent) or something hard to deal with. In comparison, you can be paid insane amounts to code skinner boxes or ad optimisation in a well-lit office.

A former boss taught me of the "law of conservation of bullshit" :-)
