First of all, food and water would be abundant and distributed evenly. People would have complete rights to the land that they work to improve and live on. If this could be accomplished, I believe much of the fighting and greed would be eliminated already. Hoarding food and property would not be permitted - basically use it or lose it.
A strong sense of community would be needed to help people find purpose. If people were taken care of and didn’t use currency to trade, my hope is that they would be busy in what they are passionate about and what best serves their community.
I think spirituality would be very important to reinforce (not dictate!) this system. There would need to be strong spiritual leaders to guide the community into seeing that they are all one working towards a common goal. And to help those who are lost to find their purpose.
