Although the IWW was built on the basis of uniting workers of industry, a rift began between the union and the Socialist Party. It started when the electoral wing of the Socialist Party, led by Victor Berger and Morris Hillquit, became irritated with speeches by Haywood. In December 1911, Haywood told a Lower East Side audience at New York's Cooper Union that parliamentary Socialists were "step-at-a-time people whose every step is just a little shorter than the preceding step". It was better, Haywood said, to "elect the superintendent of some branch of industry, than to elect some congressman to the United States Congress". In response, Hillquit attacked the IWW as "purely anarchistic".
