Roy A. Childs, Jr. (1949–1992) was a libertarian essayist and critic who counted among his early influences Ayn Rand, Ludwig von Mises, Rose Wilder Lane, and Robert LeFevre. In the 1960s, Childs became friends with Murray Rothbard, and Childs's controversial paper, "The Invisible Hand Strikes Back," was published in the inaugural issue of the Journal of Libertarian Studies. In 1977 he became a research associate of the Center for Libertarian Studies.
Ludwig von Mises: "This, then, is freedom in the external life of manthat he is independent of the arbitrary power of his fellows. Such freedom is no natural right. It did not exist under primitive conditions. It arose in the process of social development and its final completion is the work of mature Capitalism." - Socialism
