Can you try to tally the list of actually innovative companies (let's say in tech or bio) headed by MBAs vs. non-MBAs? The only notable MBA ceo of a massive tech company from history was Steve Ballmer and let's at least agree there's no consensus if he was any good for Microsoft. Tim Cook is arguably good, but that's just 1/5 if we are looking at top 5 tech. Even the "business" CEO of Google, Eric Schmidt, is not an MBA.
