I guarantee you that a run of the mill MBA program will say something about institutional knowledge being important.
You’re needlessly and unjustifiably finding an excuse to dunk on something that you know people here dislike, despite it having very little to do with the actual topic. Which…fine. But you’re also so keen to do it that you aren’t even correct. Please stop projecting every gripe you have with your boss onto this mythical “evil MBA”.
