The act of having children makes people more desirable citizens.  Not only does parenting teach responsibility, but it also triggers such feelings as love, compassion and helps develop such features as patience, devotion, tenderness, understanding. For instance, if parents learn the benefits of being patient towards their children, they are more likely to react patiently in other life situations, which in turn will lead to less aggressive society. Therefore, the more people have children, the more desirable our society becomes.
