"John Marangos examines the viability of socialist economic systems from a social science perspective instead of from a narrow mainstream economics perspective. Consequently, he provides a much better understanding of their successes and failures. This is certainly needed in the light of the world-wide crisis caused by the adoption of neoliberal policies." - Frederic S. Lee, Professor of Economics, University of Missouri-Kansas City, USA and Editor, American Journal of Economics and Sociology
