The way of life with the sufficiency or moderation, a balance not encroach others, is moral or economic justice because you will stay far away from greed and not encroach others.
Mahatama Gandhi, the Indian Leade, mentioned about sufficience that "The earth has enough for man's need but not for man's greed." That means the world can meet the need of every human being sufficient but not enough to greed voraciously.
