I've worked for the really rich. In my experience/opinion I don't think they're evil but are focused on having more for the sake of having more. They grew up in such a way that they believe they are more skilled/harder working therefore more deserving of wealth than others. They also resent those that don't do what they do but complain about not having enough wealth (even though society would stop functioning were that to be the case).
There's usually something missing from their combination of empathy and understanding which would allow them to care about the negative ramifications they're having. Look at Bill Gates, I don't think he's a bad person but he hurt a lot of people in industry and consumers to build Microsoft to what it is by destroying the competitive landscape. Steve Jobs is a better example, he proactively colluded to suppress wages and paid money for an organ that would only prolong his life but could have saved someone else's (seriously, I consider that an evil move).
One suggestion for you, it sounds like you're very angry about your current work environment. Maybe it's time to find a new place?
