This article examines the ideology and principles that inspired the privatization of social security in Chile during the Pinochet regime. The article highlights the role of the state in the establishment of a fully funded, defined contribution system, as well as the importance of the transmission of ideas from the halls of the University of Chicago to Chile's centers of power. In the case of Chile, the ideas of freedom espoused by Milton Friedman and Frederick von Hayek were applied by a repressive authoritarian regime that violated human and political rights. Furthermore, these ideas served to legitimize a political and economic system based on the deprivation of freedom. Although social security reform was a critical component of a revolution going on in Chile in the 1970s, the ultimate purpose of this article is to show that the effects of this reform are by no means limited to Chile. The Chilean reform has been adopted by countries in Latin America and other parts of the world, and it has critically affected those societies as well. The article shows that the establishment of the fully funded, defined contribution system has been very costly, both for the state and the insured, while coverage has dramatically declined. The article concludes that the market economic reforms have enhanced only the freedom of those who could take advantage of the new economy, and that few of the promises made during the Pinochet regime by the neoliberal economists came true.
