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: "In relation to the immense sacrifices that the state demands of the individual through the blood tax, it seems rather incidental whether it compensates the soldier more or less abundantly for the loss of time that he suffers from his military-service obligation." - Nation, State, and Economy
