I don't think you understand what you think you understand. For one thing, if you look around, managers do not all have MBAs. The manager I had for the longest was a previous analyst who didn't even have a college degree.
The difference between classes or tribes is their value system. The more you rationalize why your tribe is superior, the less chance you will ever be able to switch to another. So ask yourself if you really want to feel superior, or to prove yourself?
>Would you care to show me where you think I claimed 100% of managers have MBAs?
You wrote it was a "vital qualifier" to join the managerial class. You didn't 100% commit to saying it was necessary, but without that implication, I don't think you have really said anything.
