Your original assertion was generic; that a janitor has as much impact on market cap as a CEO. So let's stick with that. Consider: the CEO of Ford decides Ford will no longer sell petrol based cars (getting the board to go along with it too) and then executes that strategy. If it succeeds then the market cap of Ford will increase. If it fails then it will decrease. On the flip side, no matter how clean a janitor can make the facilities, he can't dictate corporate strategy and Wall Street doesn't care how clean Ford's bathrooms are. This doesn't diminish the importance of a good janitor, but let's be honest about the limits of their impact.
