In a recent CNBC interview, Senator Rand Paul tempered some of his recent remarks about the alleged horrors of vaccination by claiming that he only opposes vaccine mandates because they infringe upon parents’ freedom. When confronted with the question of whether or not discouraging vaccination is a threat to children’s health, Paul launched into a meandering consideration of public health and liberty that concluded with the assertion that “the state doesn’t own your children, parents own the children.”

Paul’s bizarre rendering of the parent-child relationship as unilateral ownership is not the most unhinged thing a well-regarded libertarian has ever said about children. In fact, libertarians exhibit a historical inability to adequately explain how parents should relate to their children, why parents are obligated (if at all) to care for their children, and whether or not moral nations should require that parents feed, clothe, and shelter their children within a libertarian frame.

Consider Lew Rockwell, former congressional chief of staff for Rand’s father, Ron. Rockwell, who may or may not have had a hand in composing the now infamously racist and homophobic slew of newsletters sent out to Ron Paul fans between the late '70s and early '90s, is a professed fan of child labor. Complaining of laws that prevent, among other things, second-graders from operating forklifts, Rockwell opines that “we are still saddled with anti-work laws that stunt young people’s lives.” Like Rand Paul on vaccine mandates, Rockwell sees child labor laws as government overreach. “In a free and decent society, decisions about these matters are for parents, not bureaucrats,” Rockwell writes, referring to whether or not schoolchildren should be breadwinners. The type of society Rockwell envisions here hardly seems "decent," but it would certainly be "free" in the way Paul imagines, and in that sense it is perfectly libertarian.

Rockwell’s mentor, Murray Rothbard, one of the twentieth century’s more famous libertarians, was similarly fond of kids in the workplace. Rothbard imagined that laws against child labor were passed in order to artificially inflate the wages of adults, who viewed children as competition capable of underbidding them. “Supposedly ‘humanitarian’ child labor laws,” Rothbard remarks in his book The Ethics of Liberty, “have systematically forcibly prevented children from entering the labor force, thereby privileging their adult competitors.” While the real impetus behind child labor laws was child welfare, it is telling that Rothbard tended to look upon kids with a suspicious eye, and his ethics bear out this cold approach. Later in The Ethics of Liberty, Rothbard, in keeping with the libertarian exaltation of personal freedom, argues that “no man can therefore have a ‘right’ to compel someone to do a positive act”—that is, because all people are free, by his account, your rights cannot impose positive actions on others. This means, Rothbard goes on, that a parent “may not murder or mutilate his child, and the law properly outlaws a parent from doing so. But the parent should have the legal right not to feed the child, i.e., to allow it to die.” He concludes that “the law, therefore, may not properly compel the parent to feed a child or to keep it alive.” To do so, for Rothbard, would be pure government overreach.

Such dark fantasies are not restricted to the weird world of libertarian academia. Williamson “Bill” Evers, formerly a libertarian candidate for congress and advisor to the McCain 2008 campaign, also argues that there should be no laws preventing a parent from, say, starving an infant to death. In an article published in the Journal of Libertarian Studies, Evers concludes, “We have considered the hypothesis that there should be an enforced legal duty of parents to support their minor children. Having found the various reasons advanced in support of this duty inadequate, we can only conclude that no such duty exists … one has to regard the notion of a legal duty of parents to support their children as without merit.” Evers allows that parents might be morally obligated to do something for their children, but also that morals should not be legally enforced. Therefore, vaccination, labor, and finally whether or not to give one’s children the necessities of life ultimately comes down, for these classic libertarian thinkers, to the free will of the parents.
