Question: Isn't mandated child support basically just welfare for needy children? What is the moral difference between compelling parents to support their children and compelling all people to support the needy in society? Many critics of the welfare state believe that parents should be compelled to support their children with basic levels of physical sustenance and education, such that failing to provide these constitutes violating children's rights. But how is that different from compelling people to support other needy or vulnerable people? Is the blood relationship what creates the obligation to support the child – and if so, how?

Question: Should a man be able to prevent his pregnant girlfriend from aborting his baby? Sometimes, a man will get his girlfriend pregnant accidentally, and they disagree about what should be done. If the man wants the woman to carry the pregnancy to term, whether to give up the baby for adoption or him take sole custody, while the woman wants to get an abortion, should he be able to prevent her? It's his baby, shouldn't he have some say?

Question: Should a man unwilling to be a father have to pay child support? Suppose that a man and a woman have sex, and the woman becomes pregnant – even though the couple used contraception based on a shared and expressed desire not to have children. If the woman decides to raise the baby, should she be able to collect child support from the man? What if they'd never discussed the possibility of pregnancy? What if they didn't use any form of birth control?
