Under capitalist forms of production, the value of the aggregate social product is divided into three parts: one corresponding to the value of the constant capital, the second to the wage total, i.e. the variable capital, and the third to the aggregate surplus value of the capitalist class. In this composition, the portion corresponding to the variable capital is relatively on the decline, and this for two reasons. To begin with, the relation of _c_ to (_v + s_) within _c + v + s_ changes all the time in the direction of a relative increase of _c_ and a relative decrease of _v + s_. This is the simple law for a progressive efficiency of human labour, valid for all societies of economic progress, independently of their historical forms, a formula which only states that living labour is increasingly able to convert more means of production into objects for use in an ever shorter time. And if (_v + s_) decreases as a whole, so must _v_, as its part, decrease in relation to the total value of the product. To kick against this, to try and stop the decrease, would be tantamount to contending against the general effects of a growing labour productivity. Further, there is within (_v + s_) as well a change in the direction of a relative decrease in _v_ and a relative increase in _s_, that is to say, an ever smaller part of the newly created value is spent on wages and an ever greater part is appropriated as surplus value. This is the specifically capitalist formula of progressive labour productivity which, under capitalist conditions of production, is no less valid than the general law. To use the power of the state to prevent a decrease of _v_ as against _s_ would mean that the fundamental commodity of labour power is debarred from this progress which decreases production costs for all commodities; it would mean the exemption of this one commodity from the economic effects of technical progress. More than that: the 'declining wage rate' is only another expression of the rising rate of surplus value which forms the most powerful and effective means of checking a decline of the profit rate, and which therefore represents the prime incentive for capitalist production in general, and for technical progress within this system of production in particular. Doing away with the 'declining wage rate' by way of legislation would be as much as to do away with the _raison d'être_ of capitalist society, to deal a crippling blow to its entire system. Let us face the facts: the individual capitalist, just like capitalist society as a whole, has no glimmering that the value of the product is made up from the sum total of labour necessary in the society, and this is actually beyond his grasp. Value, as the capitalist understands it, is the derivative form, reversed by competition as production costs. While in truth the value of the product is broken down into the values of its component fragments _c_, _v_ and _s_, the
