Nice to see more empirical backing of the Bullshit Jobs theory 
The research found that people working in finance, sales and managerial roles are much more likely than others on average to think their jobs are useless or unhelpful to others.
The study, by Simon Walo, of Zurich University, Switzerland, is the first to give quantitative support to a theory put forward by the American anthropologist David Graeber in 2018 that many jobs were "bullshit"—socially useless and meaningless.
graeber talks about this in the BS jobs book. he talks about how the feeling of doing something useful is supposed to be pay in and of itself and how its used to make other workers feel resentful if you make demands re conditions&pay.
I read bullshit jobs via audiobook while doing useful work. That phenomenon changed my brain chemistry. Cause my decision was going "well then I don't care about being useful." and have pivoted to a position much less useful to society.
