I kind of questioned Graeber's thesis but I do think he was onto something. I think most management jobs are bullshit jobs in that they don't contribute very much but are easy and well paid. You then have a whole underclass who actually do the work. It's not too different from ancient Greece where the society depended on slavery to function. The pandemic showed that very few of our jobs are essential. A large proportion of the population in the west could be not working yet society still functioned. It's only when things slow down in the east (where things actually get made) that it causes problems.
