The power to determine the quantity of money… is too important, too pervasive, to be exercised by a few people, however public-spirited, if there is any feasible alternative. There is no need for such arbitrary power… Any system which gives so much power and so much discretion to a few men, [so] that mistakes – excusable or not – can have such far reaching effects, is a bad system. It is a bad system to believers in freedom just because it gives a few men such power without any effective check by the body politic – this is the key political argument against an independent central bank.
