Creating shareholder value is what drives American capitalism. The theory is that as management creates value for the owners, other stakeholders in the business also benefit.
Of course, that assumes an enlightened self-interest by investors, managers, workers and suppliers to avoid damaging the enterprise by being too greedy.
Sadly, there is nothing enlightened about prodding General Motors to explore a possible equity entanglement with Nissan and Renault, although it is about the self-interest of one shareholder.
Remember that nonsense about how Kirk Kerkorian planned to be a passive investor who saw an opportunity to make a killing?
Kerkorian doesn't have the patience to be a passive investor. He's an 89-year-old gambler who made a bad bet and is scrambling to win as many blue chips as possible before the Grim Reaper cashes him out.
