I have mentioned before Lawrence Lessig's work to remove the inequitable distribution of power through money and the dependency corruption that is pervasive in US politics, esp. at the federal level. His book Republic, Lost is a challenging read. He recently gave a talk at the Long Now Foundation that I highly recommend. Please do listen to it. Well worth an hour of your time.
