The miners’ union denies, in effect, the class struggle, and vainly seeks to harmonize the economic interests of these two antagonistic classes—the exploiting masters and the exploited wage-slaves; the robbers and the robbed. It cannot be done; not permanently at least; and if it be done even temporarily, it is always at the expense of the wage-slaves. Such an organization as that cannot truly serve the best interests of the working class. It is impossible. There are many who concur in these views, yet insist that the organization must be changed from the inside; that it can only be brought to its proper position by “boring from within.” I deny it. It is historically impossible. This organization has practically run its course. It has fulfilled its mission as a labor union, whatever that has been. It is now practically in charge of the mine owners; and the only way the miners can get away from that situation is to sever their relations with that capitalist-controlled union and join and build up one of their own upon the basis of the class struggle; and then they will be in position to fight the capitalist class with some chance of success. The most important fact in all the world for workingmen to take cognizance of is the class struggle. The Industrial Workers express economically the interests of the working class in that struggle. The Industrial Workers declare that there can be nothing in common between the exploiting capitalist and the exploited wage-worker; that there is inevitably a struggle between them, and that this struggle cannot end until the capitalist class is overthrown, and the wage-system wiped out. Then and then only can there be an end to class rule. Now, if you are a workingman and if you believe that you have an economic interest in common with that of the capitalist who employs you, remain in the old trade union. That is where you belong. If that is your conviction we do not want you to join the Industrial Workers. You do not properly belong to us. You do belong to the American Federation of Labor and its affiliated organizations. But, if you believe, as I believe, that the working class have economic interests of their own, separate and apart from and in conflict with the economic interests of the capitalist class, then you should, and sooner or later will have to, sever your relation with the old trade union and join the Industrial Workers, the only union organized upon the basis of class struggle. And now, let me ask, have we a class struggle? The answer comes of itself. This struggle finds expression daily, hourly, in strikes, in boycotts, in lockouts, injunctions, riots, assaults and bloodshed. It is not an unmixed evil, however, for in this great world-wide class struggle, that is shaking the foundations of civilized society everywhere, there are being wrought out the most important problems of our modern civilization.
