I really recommend the three short videos made by Brandy here. She makes some powerful arguments in favour of the tenets of The Venus Project and The Zeitgeist Movement.
Two have stuck out in my memory.
(1) The change to an RBE will probably take more than our lifetime, but if we never start something that can't be finished in a lifetime, it'll never happen.
(2) Whichever way you look at it, the "9-11" attacks were human beings killing other human beings (both in the planes and in the twin towers). Brandy says that's an 'inside job' whoever planned it and/or carried it out.
