It seems strange that someone with the business acumen to become the world's richest man would not look on the inefficient and broken charity and aid systems as an opportunity to create a better solution. There won't be good new jobs in places where there isn't reliable electricity or clean drinking water.

Like most aging industries, the "making the world better" industry is definitely in need of some disruption. We see newer entrepreneurs talking about this space more and more, so I wonder how long it will be before the richest entrepreneurs start looking at new ways of solving these problems.
