If you have the opportunity to take a look at the content of your typical business administration book, or even the Harvard Business Review magazine, they essentially are collections of success stories. Instead of setting the narrative, they go and say “this or that worked/didn’t work, to get this company out of a slump”.
The issue, I believe, stems from the fact that “bringing in the MBAs” happens when a company doesn’t hit inflated targets, and for that you have to thank the c-suite, which isn’t necessarily a bunch of kids with master degrees.
