I think it will be possible to create a society in the future where people only work if they want to.
Economic theory says that you only need 3 things to create any good - land, labour, and capital. The labour bit is why everyone has to work to earn a living. Payment for labour (ie wages) goes up because increases in capital enable labour to become more productive. Basically what was once done by people is now done by machines.
Theoretically, the only thing stopping us from creating a workless society now is the fact that there are certain economic tasks which need intelligence, which means only humans can do them.
If you believe that we can develop true artificial intelligence (which is another debate in itself) then humans would not be needed in the productive process at all. If we did ever reach that stage then all we would need to do is build up our capital stock (ie build lots of machines, and AIs) until we have enough productive capacity to fulfil everyones reasonable wants.
Of course the fact that it is possible to reach that stage doesn’t mean it will happen. An economy based on machines and AIs taking the place of humans would be radically different from the free market system we have today, and would likely not involve money as we know it today. The transition between the two economic systems would be very difficult.
Additionally, the most influential groups in our society (ie the rich and successful) would likely oppose any change, as they’re doing very well out of the current system. And there will those opposed on ideological grounds believing that it is right that people should have to work for a living.
So yeah, i think that it will be possible in the future, but will it ever happen? Who can tell…
