Well, actually, I don't. For 35 years I've taught what Michael Porter believes and Joseph Schumpeter believed, which is that firms do not exist to make profit. They do not exist to maximize shareholder wealth. I've been teaching this in every course for 35 years. Firms exist to create a product or a service that we consumers want to buy, and if they are successful at value creation for the consumer, then, yes, their profits will go up and their market share will go up, but that is an outcome of successful value creation.
No, I do not celebrate shareholder-value maximization. I've been a critic of it for a third of a century. The purpose of a firm is to create products or services that you and I wish to buy and then to try to differentiate its products, through innovation, to do that, and to create a better mousetrap or a better iPhone.
