Social equality, a core value of the children's liberation movement, is a principle that holds that all people are entitled to equal rights to their life, liberty and property regardless of age. It does not mean that people are necessarily equal in intelligence, wisdom, or any other ability or attribute. People do in fact differ in their capacity for using available resources in ways that will produce satisfaction. Children often lack some of the ability that adults have to act in ways that will bring about desired benefits; e.g. a child may be too weak to do heavy labor on a construction site, or may be unskilled in the advanced mathematics required to design a jet aircraft. Child liberationists hold that a child still has the right to attempt such tasks if he owns resources that he wishes to devote to those purposes, or if someone has resources he is willing to place at the child's disposal.
