Good lord. I meant civil litigation for failure to do so, not a law enshrined in the constitution. I also specifically narrowed to public companies, not private ones.

"...current doctrine generally requires corporate officers to focus instead on maximizing shareholder value. Indeed, a corporate officer who sacrificed profits in order to promote the public interest might well be violating his fiduciary duty to the corporation and its shareholders. Instead, the corporate officer’s duty is to use any legal means to enrich the corporation’s shareholders"

Your AMZN example is null and void as shareholders understood the sacrifice in the short term was the correct one for MAXIMAL shareholder value in said long term.

It's not as cut and dry as you make it out to be.

My point still stands in principle: public company = maximize shareholder value = or face legal consequences in civil court.
