Müller-Armack was a central figure of the "Cologne school." He always pointed out that the economy had to serve humanity. A regulatory environment should provide the basis for a form of competition that was to the best for all people.
After 1952, he worked in the economic ministry under Ludwig Erhard (CDU) as section chief of the newly founded policy department (Grundsatzabteilung).
