No one here has brought this up so I'll venture in.....
Since the 1960's - 70's there has been an ongoing debate over
whether corporations owed duties only to shareholders (a narrow duty to make a profit) or
whether that duty was broader and included stakeholders (shareholders & non-shareholders who are impacted by corporate decisions). In the U.S. shareholder-capitalism won the argument until roughly twenty years ago. Since then, stakeholder-capitalism in the guise of "sustainability" has been gaining ground. In Europe, shareholder-capitalism won back then and continues to prevail. Corporate law developed accordingly.
I agree with the earlier comment to the effect that without communism as an alternative, capitalism is running amok and veering toward its darker exploitative side.
However, roughly thirty years ago smart people started talking about the idea of sustainability or sustainable capitalism. The "definition" has been all over the map since then but essentially, sustainability seeks to embed a stakeholder-capitalism ethic into corporate behavior as a mechanism for mitigating the excesses of capitalism.
Without some mitigation, "pure capitalism" will cannibalize itself because it is a model reliant on cheap/ free and abundant natural and human resources combined with the easy ability to externalize costs. Proponents of sustainability argue that a new model of capitalism is necessary and they've gained a lot of ground, especially in the last decade. For example:
The CDP demands that the world's largest companies disclose their performance on GHG emissions and companies respond, disclose information, and submit to CDP's "Leadership" assessments.

But much of it arises from CEO-level commitments and it is changing how business is done. I've been working in this area for about 5 years and I've seen big progress just in that time. There is a large and growing cadre of committed professionals who see this as the next-generation capitalism, a capitalism for the long-haul, if you will.
And, FWIW, corporate leaders pay attention to their customers. If customers demand commitments to sustainable products, fair treatment of workers or animals, transparency in corporate disclosure, water- and waste-neutral operations, etc. then companies WILL DO IT.
