A Critique of the Segmentation Theory of Racial Discrimination
Marxists have traditionally argued that racism and national chauvinism are tools of the capitalist class, used to divide the working class (Perlo 1975; Reich 1981). The main reason for dividing the working class is to ensure the maximum exploitation of the working class and to prevent them from organizing to overthrow the capitalist system. The implication is that racism and national chauvinism are opposed to the objective interests of all workers.
