Should the Products of the Labor of the Community Be

Should the products of the labor of the community be shared equally? Or, should those who have worked harder and longer get more? Or, should those whose needs and wants are greater get a larger proportion? Or, should those who are more valuable to the community get more? A sense of natural justice has been appealed to on behalf of every one of these options. There are good arguments pro and con for all of them. Try to list as many as you can.
