Joan Robinson (girl economist): Richard T. Ely Lecture to the American Economics Association, 1972 (published in AER, 1972, 62(1/2): 1-10) "A sure sign of a crisis is the prevalence of cranks. It is characteristic of a crisis in theory that cranks get a hearing from the public which orthodoxy is failing to satisfy. ... The cranks are to be preferred because they see that there is a problem."
You go, girl! As the Dutch said while fighting the Spanish: "It is not necessary to have hope in order to persevere."
