We keep rewarding the wrong people, it's no wonder things are as they are.
It’s not as important in a new market, but if you are in a fiercely competitive market (eg real estate) some rule breaking to advance you against the competitors is probably helpful to make a billion dollar company.
I.E. Uber, Deliveroo, WeWork etc might not be the hugely valuable companies they are today if they didn’t break the rules, regardless of how morally wrong that might be.
It yet remains to be seen whether they are a "hugely valuable companies" or just smoke and mirrors for gullible investors in an era of almost free credit.
So they are absolutely valuable.
(ie something is valuable if you can sell it right now for a lot of money - so all these companies are highly valuable).
Once you have got the $22B you have probably already done most of the incredibly ‘bold’ parts you need to do to set the company off.
That's what I like to tell myself.
It does not matter if you are dead before people realise your contribution to the world. For example, Galileo won.
For example, there are people who hold the Scientific Revolution ushered by Galileo&co to be directly responsible for genocides and suffering (of humans and otherwise) on an unprecedented global scale.
In the long-term view suggested by inglor_cz, "change this world a little for good" is really just feel-good moralistic posturing. Without specifying "good for whom?", and "on what time scale?", it's a vacuous concept.
That said, you would benefit from learning about effective altruism, it is a philosophical and social movement that advocates using evidence and reason to figure out how to benefit others as much as possible, and taking action on that basis.
What wins is apathy; indifference to adopting new agency.
Stop believing typical meat bags are anything more; that a network of rich exists is entirely due to belief in them. They’re just meat bags. Their figurative identity is not sacrosanct.
It helps alot in life, project management, planning etc etc.
