DuBois takes on the labor unions in this essay. He confesses that he had always inveighed against color discrimination by employers and by the rich. He knew at the same time in silence that it was practically impossible for any colored man or woman to become a boiler maker, book binder, electrical worker, a plumber or a printer or a textile worker, carpenter, or any of a dozen other important employments, without encountering the determined opposition of the united labor movement.
