Thomas Lambert is an Indiana academic.
Approximately 28 labor activists, activists for single payer health care, gay rights, an end to mountain top removal, voter rights for ex- felons, students for socialism, and campaigners against racism and war in Afghanistan came together on Saturday, September 19 2009, in Louisville to share information and action plans at the semi-annual Midwest Committees of Correspondence for Democracy and Socialism meeting.
Thomas Lambert, Lecturer, Department of Economics, Indiana University Southeast, New Albany, Indiana, presented results of a study he had done that showed the continued relevance of Marx’s theory of exploitation. Using contemporary national and global data, the Marxian formula that emphasizes capitalism’s expropriation of the surplus value produced by workers remains an excellent predictor of levels of inequality within countries and in the international system. Higher rates of exploitation in the Marxian sense, he concluded, lead to greater inequality.
