Management are not thieves. They are merely indulging in the practice of capitalism. It is legal. Ethics is not something of their concern. The ones who take the risks of investment are the only ones who question the ethics. Businesses have never considered the customer as always right. And that's what investors are, customers of the corporation. Corporations are people. If you know who owns your future, your investments will be more informed. It's legal and it's law. The ethics question is much discussed between philosophers after a couple of drinks. It's an interesting diversion.
