Someone: - created a new business, - employed 1000s of people, giving them better opportunities, - created something valuable to improve the lives of consumers, and - did it for so many people at such scale that they became a billionaire, and somehow you're complaining about the amount of their contribution? That said, the origin of your wealth is also important. A politician that got it simply by stealing via the government didn't contribute anything.
