Concentration and co-operation are conditions imperatively essential for industrial advance; but if we allow concentration and co-operation there must be control in order to protect the people, and adequate control is only possible through the administrative commission. Hence concentration, co-operation, and control are the key words for a scientific solution of the mighty industrial problem which now confronts this Nation.
Theodore Roosevelt, who is quoting from Charles Van Hise at the Progressive Party Convention. Notice the language used, it's consistent. Concentration, and Cooperation. This one is the interesting one, from Supreme Court Justice Louis Brandeis: (A Wilson appointee)
The proper role of the government is to encourage not combination, but co-operation.
