A importância do trabalho de Milton Friedman é bem colocada neste texto de Ben Bernanke:
"In preparing this talk, I encountered the following problem. Friedman’s monetary framework has been so influential that, in its broad outlines at least, it has nearly become identical with modern monetary theory and practice. I am reminded of the student first exposed to Shakespeare who complained to the professor: “I don’t see what’s so great about him. He was hardly original at all. All he did was string together a bunch of well-known quotations.” The same issue arises when one assesses Friedman’s contributions. His thinking has so permeated modern macroeconomics that the worst pitfall in reading him today is to fail to appreciate the originality and even revolutionary character of his ideas, in relation to the dominant views at the time that he formulated them."
