According to far too many, a corporation's sole duty is to the enrichment of its shareholders. I speak not of an ideal capitalism, but of capitalism as it is practiced.
Oh, I agree that that's what corporations should be doing -- I just trust my government to give them laws and regulations to follow, to steer the lumbering economic engine to the goals that we as society value. (I also tend to think that companies that people think are good tend to last and have broad social support, so doing good does have merits even to bloodthirsty capitalists).
If companies break those laws or regulations, the penalties should be extremely steep (I imagine we probably agree on this bit, but let me know if not).
