How much power is concentrated in the hands of individuals... It's great that Gates is choosing to use that power philanthropically, but it also raises questions about the long-term role of private wealth in solving public problems.
This is great, but what about the rich people who don't give? Won't they just continue to get more and more power?
The scales are tipped and this is not sustainable. Gary Stevenson is a bit extreme, but he's not wrong about centralization and it's dangers!
