394 World Federation and Social Progress 



organization on the basis of mutual aid, will 

 become an irresistible army victorious in the 

 struggle against one after another of the foes of 

 humanity. 



Many factors favourable to federation are 

 already powerful and are steadily growing in 

 strength. In many respects the world is even now 

 a unity and the task of federation is to give open 

 political recognition to the economic, social, and 

 intellectual facts of vital interdependence. As 

 the result of the advance of science and the con- 

 quests of engineering, the earth has become smaller 

 every year, so that division of labour is now es- 

 tablished upon a planetary scale. Capital has be- 

 come international and by means of the telegraph 

 and cable, stock exchanges in all the financial 

 centres of the world have established a sensitive 

 nervous system by which an injury to any part 

 of the social fabric is felt by all the other parts. 

 The migration of labour is taking place upon a scale 

 unknown since the folk wanderings of primitive 

 times, and as a result all the problems of social 

 welfare and of attaining high standards of life and 

 civilization have become international problems. 

 In many cities of the United States two-thirds of 

 the inhabitants are foreign-born or children of 

 foreign-born parents, and the solution of the immi- 

 gration problem goes back to its roots in wrong 

 social conditions, absentee landlordism, and other 

 forms of injustice in Italy and South-eastern 

 Europe.
