Agree with starting by showing the problem and how it can be solved. As @BitcoinSanity says, most people know there's something wrong with the way things work, but they just don't know exactly what it is. Inequality is a terrible problem worldwide and most people think that more state intervention, taxes and food stamps will solve it, but that's what we've done so far, so more of the same won't do it. The system is built in a way that produces that outcome, and it's mostly about how money works. But mostly just start writing something, whatever, you can always trash it and start over again.

The link shows exactly what I said, Oxfam has good data and their idea for fixing the problem is more taxes (sigh)
