Mr. Mann agreed with him. In a speech published in the _International Socialist Review_[599] he expressed his belief that "if the fine energy exhibited by the I. W. W. were put into the A. F. or L. or into the existing trade-union movement ... the results would be fifty-fold greater than they now are." He went on to "urge the advisability, not of dropping the I. W. W., but certainly of dropping all dual organizations and serving as a feeder and purifier of the big movement." William D. Haywood replied that "it might as well be said that if the fine energy exhibited by the I. W. W. were put into the Catholic church, that the results would be the establishment of the control of industry."[600] He went on to show that it is well-nigh impossible for the unskilled man to get into the A. F. of L., even when he does desire to do so, because of what Haywood characterizes as "a vicious system of apprenticeship, exorbitant fees," _etc._[601] Mr. Haywood's fellow-worker, Joseph J. Ettor, joined him in his attack on Tom Mann's position: The theory that what is needed to save the Federation is the energetic and vigorous men who are now in the I. W. W. is on a par with the "socialist" advice of [_sic_] how to save the nation; but we don't want to save the Federation any more than to save the nation. We aim at destroying it. The Socialists advised us to roll up our sleeves and become active politically within capitalism--"We must capture the government for the workers," _etc._ We tried, but the more we fooled with the beast the more it _captured us_. Our best men went to "bore from within" capitalist parliaments, and city councils, only to be disgusted, thrown out, or fall victims of the game and environment in which they found themselves.... We learned at an awful cost particularly this: That the most unscrupulous labor fakers now betraying the workers were once our "industrialist," "anarchist" and "socialist" comrades, who grew weary of the slow progress we were making on the outside, went over, and were not only lost, but ... became the greatest supporters of the old and [the] most serious enemies of the new.[602] Mr Mann's attitude was not appreciably changed during his trip through the United States. His reaction to the situation so far as the principle of "dual unionism" is concerned is explained in an article contributed to a French journal. He wrote: As the situation appears to me after many deep conversations and discussions with working men of all conditions, I say very emphatically that the I. W. W. should work in harmony with the American Federation of Labor. There is not the least necessity for having two organizations. The field of action is wide enough for all to be able to coöperate in the economic struggle....
