“The IWW's affirm as a fundamental principle that the creators of wealth are entitled to all they create. Thus they find themselves pitted against the whole profit-making system. They declare that there can be no compromise so long as the majority of the working class lives in want while the master class lives in luxury. They insist that there can be no peace until the workers organize as a class, take possession of the resources of the earth and the machinery of production and distribution and abolish the wage system. In other words, the workers in their collectivity must own and operate all the essential industrial institutions and secure to each laborer the full value of his product.
It is for these principles, this declaration of class solidarity, that the IWWs are being persecuted, beaten, imprisoned, murdered. If the capitalist class had the sense it is reputed to have, it would know that violence is the worst weapon that can be used against men who have nothing to lose and the world to gain.”

The Canton, Ohio Speech, Anti-War Speech (1918)
Context: Wars throughout history have been waged for conquest and plunder. In the Middle Ages when the feudal lords who inhabited the castles whose towers may still be seen along the Rhine concluded to enlarge their domains, to increase their power, their prestige and their wealth they declared war upon one another. But they themselves did not go to war any more than the modern feudal lords, the barons of Wall Street go to war. The feudal barons of the Middle Ages, the economic predecessors of the capitalists of our day, declared all wars. And their miserable serfs fought all the battles. The poor, ignorant serfs had been taught to revere their masters; to believe that when their masters declared war upon one another, it was their patriotic duty to fall upon one another and to cut one another's throats for the profit and glory of the lords and barons who held them in contempt. And that is war in a nutshell. The master class has always declared the wars; the subject class has always fought the battles. The master class has had all to gain and nothing to lose, while the subject class has had nothing to gain and all to lose — especially their lives.
They have always taught and trained you to believe it to be your patriotic duty to go to war and to have yourselves slaughtered at their command. But in all the history of the world you, the people, have never had a voice in declaring war, and strange as it certainly appears, no war by any nation in any age has ever been declared by the people.
And here let me emphasize the fact — and it cannot be repeated too often — that the working class who fight all the battles, the working class who make the supreme sacrifices, the working class who freely shed their blood and furnish the corpses, have never yet had a voice in either declaring war or making peace. It is the ruling class that invariably does both. They alone declare war and they alone make peace.
Yours not to reason why;
Yours but to do and die.
That is their motto and we object on the part of the awakening workers of this nation.
If war is right let it be declared by the people. You who have your lives to lose, you certainly above all others have the right to decide the momentous issue of war or peace.
