This article argues that the contributions of Marxist Dependency Theory (MDT) can provide theoretical insights for the analysis of financialized capitalism dynamics, contribute to the debate about the rise of a globalized working class, and help guide a transformative praxis in the periphery, therefore being relevant for the debate of contemporary imperialism. I discuss which traditions of dependency theories were most featured in economics literature and why I believe that MDT is marginalized and misinterpreted, focusing on the historical and political aspects of that process. Next, I debate some contributions of contemporary imperialism theory, and conclude that MDT has the potential to advance some of its core concepts and formulate a powerful synthesis.
