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: "The armament industry created militarism and imperialism, however, just as little as, say, the distilleries created alcoholism or publishing houses trashy literature. The supply of weapons did not call forth the demand, but rather the other way around." - Nation, State, and Economy
