corporate social responsibility is illegal

The 'best interests of the corporation' principle, now a fixture in the corporate laws of most countries... compels corporate decision makers always to act in the best interests of the corporation, and hence its owners. The law forbids any other motivation for their actions, whether to assist workers, improve the environment, or help consumers save money. They can do these things with their own money, as private citizens. As corporate officials, however, stewards of other people's money, they have no legal authority to pursue such goals as ends in themselves, only as means to serve the corporation's own interests, which generally means to maximise the wealth of its shareholders.
Corporate social responsibility is thus illegal - at least when it is genuine.
