criticizing the book on issues it did not actually address, such as welfare programs for the elderly or sick, something Hayek was not entirely opposed to. Easterly noted that The Road to Serfdom was about the dangers of centralized planning and nationalization of industry, including the media.<ref>{{cite news|url=https://www.wsj.com/articles/SB116355956112023480|title=Dismal Science|author=William Easterly|author-link=William Easterly|date=15 November 2006|work=The Wall Street Journal}}</ref> In Sachs' counter-rebuttal, he argued that he was addressing Hayek's foreword in the 1976 adaptation which stated that efforts to bring about large-scale welfare states would bring about serfdom, although much more slowly than under centralized planning. Sachs cited the Nordic states which remained economically free and relatively capitalist, despite a large welfare state that Hayek was wrong about such programs leading to serfdom. Gordon Tullock has argued Hayek's analysis incorrectly predicted governments in much of Europe in the late 20th century would descend into totalitarianism. He uses Sweden, in which the government at that time controlled 63 percent of GNP, as an example to support his argument that the basic problem with The Road to Serfdom is "that it offered predictions which turned out to be false. The steady advance of government in places such as Sweden has not led to any loss of non-economic freedoms." While criticizing Hayek, Tullock still praises the classical liberal notion of economic freedom, saying, "Arguments for political freedom are strong, as are the arguments for economic freedom. We needn’t make one set of arguments depend on the other." However, according to Robert Skidelsky, Hayek "safeguarded himself from such retrospective refutation". Skidelsky argues that Hayek's argument was contingent, and that, "By the 1970s there was some evidence of the slippery slope ... and then there was Thatcher. Hayek's warning played a critical part in her determination to 'roll back the state.'" Economic sociologist Karl Polanyi made a case diametrically opposed to Hayek, arguing that unfettered markets had undermined the social order and that economic breakdown had paved the way for the emergence of dictatorship. Barbara Wootton wrote Freedom under Planning after reading an early copy of The Road to Serfdom, provided to her by Hayek. In the introduction to her book, Wootton mentioned The Road to Serfdom and claimed that "Much of what I have written is devoted to criticism of the views put forward by Professor Hayek in this and other books." The central argument made in Freedom under Planning is that "there is nothing in the
