alt Hacker News> A lot of tech companies end up shooting themselves by putting too much power into the CEO, so that when the MBA takes over it turns into a corporate pillaging operation.
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.
Wall Street rarely appoints CEOs, that's the job of the board. And those members generally get there via investment into the company (usually before it goes public).
The MBAs get there often because it's who the board picks when the founder retires.
