If it is a lie, then by definition it isn’t true. I would argue that it, perhaps, isn’t true, but isn’t a lie.
I won’t debate your point (though the articles don’t, quite, say what you imply they do), and withdraw that part of my post. I will note three things: one that the laws you quote do not demand maximized profits, but also don’t say a damn thing about ethics, two, that whatever laws say it is manifestly true that corporations do not obey them all the time, and three even if they aren’t legally obligated to act amorally and selfishly it is increasingly obvious that they absolutely do. All the time.
Fundamentally, a privately held company has whatever the mores the owner has. That which is repugnant to the owner is repugnant to the company modulo the inefficiencies of management, obviously. If the owner is an amoral bastard, then the company will be as well, and seeing as companies are lightly punished for infractions, it’s a great way to let your amoral bastardry flourish.
A publicly held company however, has no real ethical compass. Its owners are fragmented enough through the complex financial structures that lie behind stock ownership that their influence is diffused into nothing. The people running it are, despite their lofty status, employees of it and are beholden to the interests of the corporation. What’s moral for the corporation is determined, thus, by what’s good for the corporation. There’s no other moral code. A bit may be around initially as a sort of founder effect, but once that wanes, the natural rapaciousness of the truly self-centered sets in.
Countries act the same way, in fact, which is why they are so often party to atrocities few among their citizenry would truly approve of and this is with and explicit notion of morality baked in (the national myths, ideals, icons, and heroes i.e. whatever is meant by the ‘american way’ as distinct from ‘truth’ and ‘justice’).
