" This orthodox Marxian view leaves an important factor out of consideration-a factor perhaps more vital to the possibility and success of a social revolution than-even the industrial element. That is the psychology of the masses at a given period. Why is there, for instance, no social revolution in the United States, France, or even in Germany? Surely these countries have reached the industrial development set by Marx as the culminating stage. The truth is that industrial development and sharp social contrasts are of themselves by no means sufficient to give birth to a new society or to call forth a social revolution. The necessary social consciousness, the required mass psychology is missing in such countries as the United States and the others mentioned. That explains why no social revolution has taken place there. "
