It used to be that the difference in productivity in most (manual laborers, artisans) was at most a small multiple. It seems inevitable under the capitalist system that increasing automation in all fields will widen the wealth gap considerably, as the most productive people become many times (perhaps many orders of magnitude) as productive as the least. The difference between someone who performs a task and someone who can program many cheap machines to do the same thing will grow much, much wider as machines become cheaper to buy and operate. The owners of those machines will become extremely rich unless wealth redistribution becomes more common. Large social changes or revolution seem like they'll become required. At some point, though, once every type of work can be done by machines, wealth could probably be redistributed in such a way that noone had to work very much. That would probably require human level intelligences, though, and then cue the great robot uprising...
