"Ludwig Erhard had by this time [1975] retired from any involvement in active politics, but apparently he had heard that my politics (and economics) were sufficiently different (that is to say similar to his own) to make a discussion appealing. I was glad to discover that the former Chancellor, as well as being the architect of German prosperity, had a considerable presence and shrewdness. He asked me a number of searching questions about my economic approach, at the end of which he seemed satisfied. I felt I had performed well in an important tutorial."
