In an environmentally sustainable, just and peaceful world, the world system would only pull in the human work it needed to remain sustainable just and peaceful. If it could reduce human work through automation it would do it gladly. But for this to work the link from survival to work via money must be broken.
People are sceptical that people would work for no reward other than the satisfaction of it. I share the scepticism, but I'm prepared to give it a go. The world is so dysfunctional now, as we destroy each other and our environment, that I'm prepared to risk this motivational problem. And anyway, if we really needed money we coulkd re-introduce it easily in the twinkling of an eye. It's just numbers in computers.
