You're describing the opposite scenario. Generally it's the founders who get a special class of shares which allows them to retain control over the company even when they own <5% of the stock. Without that the company becomes controlled by Wall St. who appoint the MBA to loot and pillage.
The MBAs get there often because it's who the board picks when the founder retires.
The main thing the special class of shares does is make it hard for them to oust the founder when the founder doesn't want to retire. Once they choose to, they either use their special votes to choose a worthy successor, or they stop caring and you get the default MBA you'd have had regardless.
