And we do codify some of those ethical and moral mandates in the form of laws and government regulations. Ultimately the only way to ensure that companies consistently behave well is to elect politicians who will force them to do so.

Why not add them to a company's charter? I guess it would scare away potential investors, but maybe other investors would be attracted by them.

I'm in the camp that doesn't believe a free society should be mandating individual morals.

Edit: leaving ethics out of this.

All laws are inherently mandates of ethics/morals.

Edit: to address the parent edit to remove “ethics” and distinguish “morals” for different treatment, the division of subjective preferences into “ethics” and “morals" (and “aesthetics”, for that matter) is fairly arbitrary and subjective in any case.

Good laws are conservative codifications of consensus morality. A just legal code forbids only what the vast majority would consider wrong regardless of the law.

When the law forbids what people don't consider wrong, it becomes tyranny.

I don't think that's entirely true; legal codes often specify things on which there is a strong preference for uniformity (or benefits which can only be gained by uniformity) but where the details of the uniform rules are not themselves a near-universal consensus independent of the law. I don't think this makes them bad legal codes. (Prohibiting driving on the left-hand side of a public roadway in the direction of travel, for instance.)
