I think you have an interesting point but I disagree with your analogy of a presidential election. The motivations for voting in a presidential election are not always financial (even though future policies could very well determine your own financial outlook..). I think you're right about investors are in it for the returns but having control can help steer your returns. If everybody thinks the CEO is not increasing shareholder value, you vote to remove said CEO. This is not always positive either as many investors want quick returns and not always have patience for visionaries..
