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.
