When the accumulation of wealth is no longer of high social importance, there will be great changes in the code of morals. We shall be able to rid ourselves of many of the pseudo-moral principles which have hag-ridden us for two hundred years, by which we have exalted some of the most distasteful of human qualities into the position of the highest virtues. We shall be able to afford to dare to assess the money-motive at its true value. The love of money as a possession — as distinguished from the love of money as a means to the enjoyments and realities of life — will be recognised for what it is, a somewhat disgusting morbidity, one of those semi-criminal, semi-pathological propensities which one hands over with a shudder to the specialists in mental disease ... But beware! The time for all this is not yet. For at least another hundred years we must pretend to ourselves and to everyone that fair is foul and foul is fair; for foul is useful and fair is not. Avarice and usury and precaution must be our gods for a little longer still. For only they can lead us out of the tunnel of economic necessity into daylight.

“In order to preserve, in a money economy, the tendencies towards a stage of equilibrium which are described by general economic theory, it would be necessary to secure the existence of all the conditions, which the theory of neutral money has to establish. It is however very probable that this is practically impossible. It will be necessary to take into account the fact that the existence of a generally used medium of exchange will always lead to the existence of long-term contractsin terms of this medium of exchange, which will have been concluded in the expectation of a certain future price level. It may further be necessary to take into account the fact that many other prices possess a considerable degree of rigidityand will be particularly difficult to reduce. All these ” frictions” which obstruct the smooth adaptation of the price system to changed conditions, which would be necessary if the money supply were to be kept neutral, are of course of the greatest importance for all practical problems of monetary policy. And it may be necessary to seek for a compromise between two aims which can be realized only alternatively: the greatest possible realization of the forces working toward a state of equilibrium, and the avoidance of excessive frictional resistance.  But it is important to realize fully that in this case the elimination of the active influence of money [on all relative prices, the time structure of production, and the relations between production, consumption, savings and investment], has ceased to be the only, or even a fully realizable, purpose of monetary policy. ”

 

The true relationship between the theoretical concept of neutral money, and the practical ideal of monetary policy is, therefore, that the former provides one criterion for judging the latter; the degree to which a concrete system approaches the condition of neutrality is one and perhaps the most important, but not the only criterion by which one has to judge the appropriateness of a given course of policy. It is quite conceivable that a distortion of relative prices and a misdirection of production by monetary influences could only be avoided if, firstly, the total money stream remained constant, and secondly, all prices were completely flexible, and, thirdly, all long term contracts were based on a correct anticipation of future price movements. This would mean that, if the second and third conditions are not given, the ideal could not be realized by any kind of monetary policy.”
