Kay Hymowitz writes,

libertarians depend on the family–an institution that, in crucial respects, is unfree–to produce the sort of people best suited to life in a free-market system (not to mention future members of their own movement). The complex, dynamic economy that libertarians have done so much to expand needs highly advanced human capital–that is, individuals of great moral, cognitive and emotional sophistication. Reams of social-science research prove that these qualities are best produced in traditional families with married parents.

Family breakdown, by contrast, limits the accumulation of such human capital. Worse, divorce and out-of-wedlock childbearing leave the door wide open for big government. Dysfunctional families create an increased demand for state-funded food, housing and medical subsidies, which libertarians reject on principle. And in courts all over the country, judges who preside over the manifold disputes occasioned by broken families are forced to be more intrusive than the worst mother-in-law: They decide who should have primary custody, who gets a child on Christmas or summer holidays, whether a child should take piano lessons, go to Hebrew school, move to California, or speak to her grandmother on the phone. It is a libertarian’s worst nightmare.
