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 loved being a librarian but had to quit because it didn’t pay a living wage. Even though it was a city job they kept most of us under 20 hours/week to avoid paying benefits, and the wage was less than $9/hour
Looking at the local librarian positions and realizing I will be paid more to clean the library than to run it was eye opening.
They’re only looking for retirees and people who are in it for the love of the game, not workers.
