I have learned that the purpose of a CEO in many (most?) companies is not to actually run the company. Their purpose is to be the human delegate that represents the corporate entity. They are empowered to act on behalf of the entire organization. This is important because a corporation of many individuals generally cannot act as one. You can sometimes get close with really, really good teamwork, but that's still not…
Also a single person for the board to hold accountable. In essence the individual that represents the company to outside groups. It doesn’t have to be this way. Other working cultures have adopted committees as the top. Is is the dominant form in US shareholder capitalism. The original post is surely satire.
Yes, they say so at the bottom of the page.
