We share generously, and respect each other's path of economic development as perfect for the discovery it holds. We are far more advanced than that. The economy would be almost nil. Being such a small society, they have no need for coin or currency. They all share and all work the same amount.
People are always glad to help and put the good of the whole society in front of themselves.
When people are hungry they simply take what they need from the stock of food and eat. Money would be used only for the purchasing of entertainment or art. Since people would know how to feed and shelter themselves by using their environment in a healthy, non-greedy way, we would want for little. There would be an economy of how much compassion is given and taken, that would be the money energy, compassion. As everyone works at what they love none resents working.
