As a professor, we talk to students about whether the shareholder or stakeholder model is most appropriate. When managers make decisions, should they be thinking only about shareholder wealth or should they be thinking more broadly? The evidence is quite clear that when you focus on shareholder wealth, the impact on Canadian prosperity is highest.
That's a philosophical question, and maybe I'm not the right person to think about it. But purely from a wealth perspective, focusing on shareholder wealth has been demonstrated to be the way that wealth and prosperity are maximized.
