American corporations are legally required to maximize shareholder return. The entire public company system in the US is a paperclip maximizer that is designed to vacuum up every bit of economic value available on the face of the earth and give it to shareholders.
With 80% of all US stock value owned by 10% of Americans[0], the emergent goal of the economy is to suck up every available cent and give it to people like Bezos and Zucker------.
For people like Bezos and Zucker------, that's a good thing. For the rest of us? Not so much.

This is a myth.

“The court may hold forth on the primacy of shareholder interests, or may hold forth on the importance of socially responsible conduct, but ultimately it does not matter. Under either approach, directors who consider nonshareholder interests in making corporate decisions, like directors who do not, will be insulated from liability by the business judgment rule.[9]”
This thread https://news.ycombinator.com/item?id=23393674 has a lot of quotes from primary sources and legal analysis, and reaches a similar conclusion: directors can largely do as they please.
Acting in shareholders interest is not strictly equal to optimizing shareholder returns.
"If the legal obligation to maximize profit for shareholders existed we would have to develop a good definition of how is is to be measured."
Translation of this bad argument: "Everyone uses words differently, so laws are impossible."
We have almost a century of stockholder lawsuits, some successful, to show how ridiculous this argument is.
However this does not need to be the case. If the owners/shareholders want they can demand the company to be responsible for the environment, to be socially responsible as well, or to do basic research instead of maximising short term profits. It just requires the majority of shareholders to want that, and right now this still isn't the case.
This is actually something I picked up from reading Milton Friedman's books, where a corporation exists to do the will of the owners/shareholders. Maybe I read it wrong but that's what I understood it as.
