> A company is a complex web of self-interested individuals maximizing their own value functions within the constraints of the overall function of maximizing shareholder value.
Maximising shareholder value is just one philosophy, popular mostly in the US and UK, and no longer so popular. It's not some universal truth or natural law. My other comment goes into more detail:

> self-interested individuals maximizing their own value functions
The rational self-interested econo-human is just a simplified abstraction useful for easily modeling economics. It's not meant to describe real people or be a normative recommendation for living.
Real humans are much more than self-interested; we are social beings who are defined - who experience the world - by caring (trigger word!), cooperating, or just giving. The theory of selfishness is provocative and widely repeated, but doesn't hold up to even a little scrutiny. Most of what humans do is for others. Humanity has supported almost no religious or moral philosophy that preaches self-interest rather than duty to others. People support Ukraine right now with little self-interest; the whole democratic and free world - the most successful political philosophy in history, with no competitors - is built on freedom for others (everyone always believed in freedom for themselves!). Scientists, soldiers, teachers, open source software ... so much is done by people not maximizing their personal value function, but because they naturally care about the others. Anyone who has really made love knows, beyond a doubt, that it is about the other person's joy. That is the psychologically normal, healthy state.
It's good news - great news! It's really that good. But it's threatening to worldviews and that's why always some people have rejected gospel[0].
