Hmmm, I got something different. I thought that Bullshit Jobs was based on people who self reported that their jobs were pointless. He detailed these types of jobs, the negative psychological impact this can have on employees, and the kicker was that these jobs don't make sense economically, the bureaucratization of the health care and education sectors for example, in contrast so many other professions that actually are useful. Other examples were status-symbol employees, sycophants, duct-tapers, etc.

I thought he made a case for both societal and economic impact.
