A powerful example of color used to make a point, a map showing that railroads were publicly owned in virtually every part of the developed world - and most of the undeveloped world - except the United States.
Vrooman was a socialist reformer who had worked for the cause across the country (Phillips 1952, 47). His book describes cases in which "one business after another, one activity after another has been taken by different countries and municipalities throughout the world from the realm of private enterprise," including "337 enterprises conducted by different governments, municipal and national" as well as "225 enterprises and activities to a greater or lesser extent controlled or restricted by the people." This compilation, he asserts, "cannot but prove to the most unwilling mind, that... the whole trend of our time is toward some form of fraternal socialism as against our present paternal individualism." Vrooman, 10.
