§ 2.The lowest rate of profit which can permanently exist, is that which is barely adequate, at the given place and time, to afford an equivalent for the abstinence, risk, and exertion implied in the employment of capital. From the gross profit, has first to be deducted as much as will form a fund sufficient on the average to cover all losses incident to the employment. Next, it must afford such an equivalent to the owner of the capital for forbearing to consume it, as is then and there a sufficient motive to him to persist in his abstinence. How much will be required to form this equivalent, depends on the comparative value placed, in the given society, upon the present and the future: (in the words formerly used) on the strength of the effective desire of accumulation. Further, after covering all losses, and remunerating the owner for forbearing to consume, there must be something left to recompense the labour and skill of the person who devotes his time to the business. This recompense too must be sufficient to enable at least the owners of the larger capitals to receive for their trouble, or to pay to some manager for his, what to them or him will be a sufficient inducement for undergoing it. If the surplus is no more than this, none but large masses of capital will be employed productively; and if it did not even amount to this, capital would be withdrawn from production, and unproductively consumed, until, by an indirect consequence of its diminished amount, to be explained hereafter, the rate of profit was raised.
Such, then, is the minimum of profits: but that minimum is exceedingly variable, and at some times and places extremely low; on account of the great variableness of two out of its three elements. That the rate of necessary remuneration for abstinence, or in other words the effective desire of accumulation, differs widely in different states of society and civilization, has been seen in a former chapter. There is a still wider difference in the element which consists in compensation for risk. I am not now speaking of the dif-
