Those progressives who are honestly confused by the concept of Black Power are in this state of confusion because they have not scientifically evaluated the present stage of historical development in relation to the stage of historical development when Marx projected the concept of workers’ power vs. capitalist power. Yesterday the concept of workers’ power expressed the revolutionary social force of the working class organized inside the process of capitalist production. Today the concept of Black Power expresses the new revolutionary social force of the black population concentrated in the black belt of the South and in the urban ghettos of the North—a revolutionary social force which must struggle not only against the capitalists but against the workers and middle classes who benefit by and support the system which has oppressed and exploited blacks.
