In his popular book, The Road to Serfdom (1944) and in subsequent works, Hayek claimed that socialism required central economic planning and that such planning in turn had a risk of leading towards totalitarianism, because the central authority would have to be endowed with powers that would have an impact on social life as well, and because the scope of knowledge required for central planning is inherently decentralized.
