I know we have our Marxist definition and all that, but it seems to be a really pervasive 
, everywhere I go. Some people I've talked to think for instance, all scientists are silver spooned and never worked a day in their life because they don't do construction, or whatever.
How do you argue with people like this? Can you?
I think that's a vagarie (sp??) of English. To me, a PMC is a person whose primary profession is being a manager, not a professional who manages. In my experience people in the latter category have 'people management duties' or are 'line managers' but that isn't their job title. I don't know if it's a distinction without a difference though. In my understanding PMCs as their own entity only really become a thing in sufficiently large organisations. I should read graeber lol
