I can see the point, but it could also be argued that a large part of the value of FB is created by the control of Zuckerberg. FB can move much faster without having to move everything past shareholders. And the shareholder's primary interests are making money.
Actually, these obligations apply to private corporations as well as public corporations. It's just that the chance of a shareholder suit is much higher in a public company.
Aren't you obligated to make the highest returns for shareholders? In that case, wouldn't performing an action that slows down the ability of a company to innovate break that promise?
That's a meaningless goal without a specific time frame. And of course, the moment you do specify a time frame, you also define the range of what you'll actually do in ways that flatly contradict what you'd do with different timelines.
For example, if you're trying to maximize cash on hand in the very short term, you simply stop paying your bills and declare bankruptcy when creditors attack. But if your goals are further out, this becomes the exact wrong strategy. Whatever your goal may be, you need a time frame to determine what is and isn't a good use of resources in realizing it.
Conversely, anyone who says "maximize shareholder value" without specifying a time frame is either a fool or a grifter. You can imagine how well things go when these types get together and "agree" on something this dangerously unbounded as a fundamental operating principle.
You get a lot of leeway. There is basically a rebuttable presumption you are acting in the companies best interest. But I wonder if that presumption should be weakened in the cases where the CEO has dictatorial powers over the company without a corresponding share of equity.
Even if you own a majority of voting shares, it's a basic principle of corporate law that you still have to treat shareholders equally, you still have to act in a way to maximize shareholder value, and you still have to consult the board & shareholders on the same issues. Owning 51% of voting shares doesn't turn the company into your private fiefdom.
Why even have an analogy. There is a perfect Example of Michael Dell wanting more control, and getting together with others to buy dell back, and its no longer publicly traded. They can not have to worry about shareholders, when the (for example) decide to buy EMC..
