Abstract
When I started the study which has been discussed in the preceding review, advertisements for an assistant were put into Le Monde and The Economist. There were about one hundred applicants, of which ten were selected for personal interview. One of them was Dr. William N. Parker who was at that time in the Ruhr, working on a study of the German steel industry. I have often said and I repeat it now, after having read his review of my book, that one of the greatest mistakes I have made was not to engage Dr. Parker as a member of my small research team. I am very gratified that he, nevertheless, has taken the trouble to penetrate so deeply into my study.
