I think focusing on these 100 individuals is counterproductive, as is saying that their money can magically fix poverty.
If we focus on the demonstrable, then we can say this: (1) income inequality is increasing, and (2) excessive income inequality lowers the quality of life of everyone, even the rich ( http://www.amazon.com/Spirit-Level-Equality-Societies-Strong... ). So, purely out of shared self-interest we shoud all be figuring out how to reduce the inequality, by whatever mechanism.
The solutions needed to structurally change inequality have to do with trade policies, laws, political coalitions, borders, cultural interaction, and many other things which have very little to do with these 100 people and how much money they have. If we could solve the underlying causes of inequality, then we wouldn't need to figure out income redistribution schemes that compensate for a broken socio-economical system.
