Does the growing economic might of regional superpowers like Brazil mean that dependency theory of the 1960s was all wrong? The answer to this and many other enigmas of development is found in Sub-Imperialism Revisited, a theoretically rigorous study by the brilliant Mexican analyst Adrián Sotelo Valencia. In analysing the 21st Century conditions of Latin America, Sotelo systematically explores the concept of "sub-imperialism" as advanced in the pioneering work of Ruy Mauro Marini. Himself a former student of Marini, Sotelo elucidates the explanatory power of a fully Marxist conception of imperialism and underdevelopment while providing considerable insight into opposing conceptions of dependency. This timely book ultimately enables readers to appreciate why radical dependency theory remains more relevant today than ever.
