The MBA is actually a "licence to learn" general management. The trouble is that some graduates and companies regard an MBA is an end point and not a beginning.
It isn't that hard to get an MBA, the workload is rather crushing to begin with, but it isn't rocket science. I did the part time years early morning lectures and worked Ten to Six instead of Nine to Five with the D. Engs. permission. You meet very interesting people from all walks, some of whom I'm still in touch with although I don't go to the endless Alumni meetings.
When you are a newly minted MBA, there are people who think you walk on water. If you are lucky, and almost drown three or four times proving this is incorrect, you start acquiring a little wisdom, and are actually useful to some employers.
