The labor movement in America has been characterized on both sides by very great violence. Indeed, the Secretary of the C. G. T., Monsieur Jouhaux, recognizes that the C. G. T. is mild in comparison with the I. W. W. ``The I. W. W.,'' he says, ``preach a policy of militant action, very necessary in parts of America, which would not do in France.''[29] A very interesting account of it, from the point of view of an author who is neither wholly on the side of labor nor wholly on the side of the capitalist, but disinterestedly anxious to find some solution of the social question short of violence and revolution, is the work of Mr. John Graham Brooks, called ``American Syndicalism: the I. W. W.'' (Macmillan, 1913). American labor conditions are very different from those of Europe. In the first place, the power of the trusts is enormous; the concentration of capital has in this respect proceeded more nearly on Marxian lines in America than anywhere else. In the second place, the great influx of foreign labor makes the whole problem quite different from any that arises in Europe. The older skilled workers, largely American born, have long been organized in the American Federation of Labor under Mr. Gompers. These represent an aristocracy of labor. They tend to work with the employers against the great mass of unskilled immigrants, and they cannot be regarded as forming part of anything that could be truly called a labor movement. ``There are,'' says Mr. Cole, ``now in America two working classes, with different standards of life, and both are at present almost impotent in the face of the employers. Nor is it possible for these two classes to unite or to put forward any demands. . . . The American Federation of Labor and the Industrial Workers of the World represent two different principles of combination; but they also represent two different classes of labor.''[30] The I. W. W. stands for industrial unionism, whereas the American Federation of Labor stands for craft unionism. The I. W. W. were formed in 1905 by a union of organizations, chief among which was the Western Federation of Miners, which dated from 1892. They suffered a split by the loss of the followers of Deleon, who was the leader of the ``Socialist Labor Party'' and advocated a ``Don't vote'' policy, while reprobating violent methods. The headquarters of the party which he formed are at Detroit, and those of the main body are at Chicago. The I. W. W., though it has a less definite philosophy than French Syndicalism, is quite equally determined to destroy the capitalist system. As its secretary has said: ``There is but one bargain the I. W. W. will make with the employing class-- complete surrender of all control of industry to the organized workers.''[31] Mr. Haywood, of the Western Federation of Miners, is an out-and-out follower of Marx so far as concerns the class war and the doctrine of surplus value. But, like all who are in this movement, he attaches more importance to industrial
