the thing that made the "MBAs are bad for business but especially bad for workers" thing make the most sense for me is I remembered the business school my school was Known For, and who their guest speakers and professors were, and pretty much all of them were former consultants and not people who actually like, ran a business
I don't think most MBAs are bad at heart, but 4 years of propaganda you must take on in order to pass when you're paying so much for school is a HUGE sunk cost that makes most people captive audiences.
And on top of that, it gives you a vocabulary set and worldview that means most people other than MBAs and middle/upper management, will start to distance themselves from you, further cementing it
