Baal HaSulam, “Building the Future Society” Chapter 3, Item1: Communism is an ideal, meaning it is moral. The goal “to work according to one’s ability and receive according to one’s needs” testifies to that.
If we live in an absolutely harmonious society of the future, where everyone is mutually connected, then everyone thinks about what he can give to this society. He must understand its needs and how he can make up for them.
There must be a serious connection between the members of society so that they do only what is necessary and do nothing in excess, since by doing so they harm nature.
That is, I do everything that others need, everything that is required of me. Every member of society does the same. Thus, we achieve complete harmony between us.
Question: Is the principle, from each according to one’s ability, a manifestation of the quality of bestowal? I use all my abilities for the sake of society. Then does to each according to one’s needs mean that I measure my needs and receive only what I need?
Answer: Or society measures them. What’s the difference? In this case, I completely trust the society.
