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.
I work at a big box store that rhymes with Ballmart. I know my job is useless. I put out way to much fruits and vegetables and the throw them away three days later. I once threw away over 170 pounds of onions cause they turned green.
