Of course the government should do something about it. But I'd bet most people would agree that killing or stealing are immoral, even in the absence of laws against it. In fact, every one here has, on innumerable occasions, not stolen something even though they could have been sure they wouldn't be caught.

Your game theory applies to people as well: if you find a wallet on the street, it doesn't make sense to give it back to the owner.

And yet, you'll find many people who do give it back. That's because we have evolved emotions such as altruism, or empathy. Those are still useful, even when most of morality has been formalised into criminal law, because societies tend to work better (and are more fun) if you can trust people, at least for the small stuff.

There's no reason we shouldn't expect corporations to follow a similar path,

True, some corporations might be altruistic, but probably not all. Murderers still exist in society, and for those we need laws to guide everyone. If all laws and police disappeared suddenly, I think it would take less than 5 years for societies to descend into complete chaos. Laws still seem necessary?

Absolutely – and in the case of corporations, I'd say there is still a lot to do to improve the law governing their behaviour. But since chances for that seem to be quite low currently, and because even a perfect legal system cannot always capture every eventuality, there should be certain behaviours that are generally frowned upon, just as there are for people.

One example I recently heard was from a woman who was fired after attending her husband's funeral. That probably happens less than a dozen times per year, and might just not warrant a law. It still shouldn't happen.

(The problem, of course, is that with people our sense of morality is largely guided by other peoples' reaction to our behaviour. Corporations will never have the same sense of shame, and the closest analogy – boycotts – rarely work)
