“The state will be able to wither away completely when society adopts the rule: "From each according to his ability, to each according to his needs", i.e., when people have become so accustomed to observing the fundamental rules of social intercourse and when their labor has become so productive that they will voluntarily work according to their ability.”
Vladimir Lenin
