What are the world's root problems?

What are the world's root problems?: Philipp Lenssen sez, "I've set up RootStrike as a minimalist site for easy referencing of root problems in online discussions. Problems -- like the corrupting system of US campaign funding -- which, if solved, would also help us a lot in solving many other problems. The site was inspired by Lawrence Lessig's book Republic, Lost, and many other sources and people."
