I'm not arguing for hard skills over soft skills. I'm asking if MBAs actually provide transferrable hard skills.
MBAs are a commodity, but they do or at least can have hard skills. I've wasted plenty of time and money on subpar market entry and expansion that could have been saved had I worked with people with some theoretical background on those.
The insight mostly comes from experiences; the knowledge of what to reference to find where to find where to find what to find could be (boringly) boiled down to rote memorization and distributed through your standard classroom practices.
