I guess they have read "Bullshit Jobs".

I've never personally felt that race-to-the-bottom capitalism would generally allow for such parasitic drains on productivity, but then again, if you're hiring on past contributions only, how would you as a non-expert in sales/marketing/etc know what makes efficiency?

I don't think your view is anywhere near as common as you think it is, but maybe in your immediate peer group there's some self-selecting cause for believing so.

I didn’t say it was my view, just what I’ve seen in expressed by others.
