People have used some sort of monetary or bartering system for thousands of years. In some cultures grain was the money, in others pretty shells.

The reality is that we never do something for nothing, especially if we don't like it or don't want to. Even things we do for enjoyment we'll stop doing if we no longer get enjoyment from it or any other reward.

We'll work to be able to eat and drink, because we have to in order to survive. We'll work to keep ourselves safe and sheltered, then we might work towards comforts and other things we enjoy when these basic needs are met.

A society where everyone gets an equal share no matter how much they contribute will only end up with enforced measures you'll need to meet in order to get that share (the stick) or the offer of extra benefits for those who contribute ( the carrot). Otherwise those doing the work will stop doing it. I believe that's why communism inevitably and rapidly evolves into a dictatorship and in order to control the masses you have to treat the controlling group (government workers) in a superior way so they will enforce measures to hold onto that superior position, as they do in China. There is quite the pecking order there. Look after your enforcers and they will help you keep everyone else in line.
