well my theory is that [given the introduction of the UN, and the regional equivolents] coupled with a growing need to be economically dependant on each other [as we currently see with the economic crisis] that communism is more possible now then it ever was [because for the first time the world truely is one global village] still a long way off, and another economic crisis would have to occur in the future making money worthless, where we would have to rely on each other in a moneyless state. feudal society perhaps.
