David Levy of the Minneapolis Federal Reserve Bank (not to be confused with George Mason’s David Levy), interviewed Milton Friedman for the bank’s The Region publication. Here is a Levy question and Friedman’s answer:
Region: If you were advising the Federal Reserve, what would you say are the unsolved economic problems of the day?
Friedman: One unsolved economic problem of the day is how to get rid of the Federal Reserve.
