The preceding investigations have shown the difficulties confronting the establishment of a socialist order of society. In a socialist community the possibility of economic calculations is lacking: it is therefore impossible to ascertain the cost and result of an economic operation or to make the result of the calculation the test of the operation. This in itself would be sufficient to make Socialism impracticable. But, quite apart from that, another insurmountable obstacle stands in its way.

As far as most socialists are concerned, recognition of these problems is obstructed, not only by their rigid adherence to the labour theory of value but also by their whole conception of economic activity. They fail to realize that industry must be constantly changing: their conception of the socialist community is always static. As long as they are criticizing the capitalist order they deal throughout with the phenomena of a progressive economy and they paint in glaring colours the friction caused by economic change.

But let us disregard the fact that up to now all socialist efforts have been baffled by these problems, and let us attempt to trace out the lines on which the solution ought to be sought. Only by making such an attempt can we throw any light on the question whether such a solution is possible in the framework of a socialist order of society.

The idea of a stationary state is an aid to theoretical speculation. In the world of reality there is no stationary state, for the conditions under which economic activity takes place are subject to perpetual alterations which it is beyond human capacity to limit.

For the naive socialist there is quite enough in the world to make everybody happy and contented. The dearth of goods is only the result of a perverse social order which, on the one hand limits the extension of productive powers, and on the other, by unequal distribution, lets too much go to the rich and thus too little to the poor.1

It follows from the principles which the socialist community must necessarily observe in the distribution of consumption goods, that alterations of demand cannot be allowed free play. If economic calculation and therewith even an approximate ascertainment of the costs of production were possible, then within the limits of the total consumption-units assigned to him, each individual citizen could be allowed to demand what he liked, each would choose what was agreeable to him.

The capital goods employed in production are sooner or later used up. This is true, not only of those goods which constitute circulating capital, but also of those which constitute fixed capital. Those, too, sooner or later are consumed in production. In order that capital may be maintained in the same proportions, or that it may be increased, constant effort is necessary on the part of those who supervise production. Care must be taken that the capital goods used up in the process of production are replaced; and, beyond that, that new capital is created.

It should be already sufficiently clear from what has been said, that under Socialism, as under any other system, there could be no perfectly stationary state. Not only incessant changes in the natural conditions of production would make this impossible; quite apart from these, incessant dynamic forces would be at work, in changes in the size of the population, in the demand for commodities, and in the quantity of capital goods. One cannot conceive these factors eliminated from the economic system.

In any economic system which is in process of change all economic activity is based upon an uncertain future. It is therefore bound up with risk. It is essentially speculation.
