My introduction to Rushkoff was Cyberia [1].
He's much more temperate now than he was in Cyberia. He has a great point, though. Restated, it's as follows: If we have abundance, why are we working for more, instead of sending the abundance to those who need it?
He seems to fall down in the mechanisms of distribution though in this article and hand-wave through it.
