Roger Martin on tradeoffs and learning from Aristotle.
The same applies to corporations. If they make it their purpose to maximize shareholder value, shareholders are likely to suffer because that cravenness turns off customers, employees, and the world in general. If they make it their purpose to serve customers brilliantly, be a fabulous place to work, and contribute meaningfully to the communities in which they operate, chances are their shareholders will be very happy.
That is my premise and I am sticking to it until someone can provide a shred of evidence that the opposite has any validity whatsoever.
