You're conflating contributing with some sort of subjective utilitarian type view. People want drugs, drug barons facilitate their availability - this is a substantial and highly productive contribution to society. To emphasize how arbitrary value systems can be, you might consider an opera singer to be contributing to society. But they're providing the exact same product to society that a footballer does - entertainment. But back on the scientists, poverty was not just the wrong word - it was the wrong idea. Most of the people you listed lived lives as pleasant as they desired and could have retired in complete comfort at various points in their career. Of course that would not make these sort of people happy. Instead they mostly lived normal lives (in terms of standard), and put their money back into furthering their research and in many ways right back into society. The same is true, though in a different way, for Bezos. He will likely never, in his entire life, spend more than a tiny fraction of a percent of his wealth on himself and his family. The vast majority of it will end up going back to society working to do his part to try to bring humanity into the space age. This isn't to say he lives modestly, but rather it exposes an interesting difference. When most people think of being a billionaire most don't think of what they could create, instead they think of what they could buy. Yet the former mindset creates wealth and the latter destroys it. When Bezos was in his teens he worked one summer at a McDonalds. He hated it. The next summer decided to found the 'Dream Institute' which was a 10 day camp for younger kids. He only got 6 signups, but at $600 a child he probably earned vastly more than he did at McDonalds and provided a great service to society at the same time. No doubt his idea was heavily incentivized by money and that's the beautiful thing about our system. When you create things, you tend to be rewarded. And on that note, I'm going to dodge the banker issue. I do agree with you there and while productivity tends to be rewarded, it's not an exclusive relationship. E.g. - those that are nonproductive can also find substantial reward at times. However, I think the issue with banks is far more complex than 'they create [and profit from] recessions so they're bad' or 'they lend money to create businesses so they're good'.
