If you approach problems on a big scale I definitely would suggest solve the problem of developing nations and their misery. I know actually it is a whole bunch of problems but I think that there is a solution which could be successful in the long-run: Educating people. Let them know what is possible and how to achieve things. Help the people, e.g. in Africa, to keep up with the world and especially also their elite which at the moment often is dominating them because they don't know better.

The OLPC project took a shot at this but besides creating net-books it wasn't too successful, to summarize, the OLPC project was ambitious but rubbish ;-) I don't know yet how to solve the problem of educating people ion those countries, especially when it comes to basic things like literacy and/or math but I definitely think it would be worth quite a lot of effort and also be a business opportunity because of scale (if not now maybe also in the long-run).

I come from a developing country where most people are fairly educated. Education is nowhere near enough. Opportunity is needed as well for some economic growth. Honesty in government is needed to encourage and support growth. In some cases, behavioral issues that are detrimental to a nation's progress is so embedded in the people that an entire change in generation is needed, otherwise the people who start climbing the ropes of success will deter others.
