This is a baseless assertion. Those at the top consistently crush unions, pollute whole regions, put down rebellions, destroy social safety nets, and so on. They do this because it is profitable. You cannot find me a billionaire who has not participated in these actions. I challenge you to try. The more of this a person refuses to participate in, the less wealthy they will be, relatively speaking, and they will be more and more susceptible to having their companies hostilely taken over. This is how the system works. At the levels of the powerful, it is never not eat-or-be-eaten. This is why it has lasted for centuries. If you really think there is any hope for change coming from within the ruling class, find me one billionaire with (ethically) clean hands. One.
I wouldn't be able to speculate about the ethics of the persons, which I do not know personally. It's not like I've devoted my life in researching their biographies either. There are campaigns like: http://en.wikipedia.org/wiki/The_Giving_Pledge

Information has been being shared this whole time. Will there be new information shared? Information being shared in a fundamentally new way? What is the second step? What sort of actions must be taken beyond the information-sharing?
We've the tools to share information, but people aren't bothering to spend time to either learn "uninteresting facts" as Millionaire MILFs of Miami is rerunning at the same time. If they do learn the facts, they rarely share them. The size of the totality of the issue at hand is after all colossal and quite daunting.
Which tools do we have that we can use to solve this problem?
Well, Reddit for one. Generally internet, freedom of speech, free press to some extent and general Western education for the aptitude to learn.
I just don't understand what you mean here--what is the "where" where people could make a difference?
People could have an impact by requiring campaigns, programs and education reforms which aim for discussing the issue at hand at all levels. Instead of having "Earth Hour" -advertisements on bus stops, sharing information about the inequality caused by ...well everything mentioned in opening post I suppose.
I don't have the answers. I really don't. At least not at this point! :D
By posting this, I just wanted gather my thoughts/knowledge under one post to organize the data and to learn more through the discussion, questions and critique on the comments here.
