The only difference would be this: that any socialistic system must divide the nett result of production--after deducting what is required for the public purposes of the whole community--in proportion to the amount of normal time contributed, and must make the distribution in products valued according to the cost of their production computed in normal time; whilst _Rodbertus_, who wishes to preserve private property, finds it necessary to add one more point to those mentioned: the periodical normalisation of wage conditions in all trades. He is very clear upon this point. "The State must require the rate of wage for the normal working-day in any trade to be regulated and agreed upon by the employers and employed among themselves, and must also ensure the periodical readjustment of these regulations and the increase in the rate of wages in proportion to the increase in the productivity of work." But _Rodbertus_ clearly perceived the difference between a normalised capitalist system and a normalised socialism, neither communistic nor anarchist. Were the workers alone, he continues, entitled to a share in the national product value, every worker would have to be credited with and paid for the whole normal time during which he had worked, and the whole national product value would be divided amongst the workers alone. For instance, if a workman had accomplished one and a half normal day's work in his normal time working-day, he would be credited with 15 work hours, and paid accordingly; if he had only accomplished half a normal day's work in the whole of his normal time working-day, he would be credited with only five work hours. The whole national profit, which would be worth x normal work, would then go in labour wage, which would amount to x normal work. But such a state of things, which may exist in the imaginations of many leaders of labour is, according to Rodbertus, the purest chimera: "In no condition of society can the worker receive the whole product of his normal work, he can never be credited in his wage with the whole amount of normal work accomplished by him; under all circumstances there must be deducted from it what now appears as ground rent and interest on capital." Ground rent and interest on capital are, according to Rodbertus, remuneration for "indirect work" for the industrial function of directing or superintending production. "If therefore the worker has accomplished, in his normal time working-day, 10 hours of normal work, in his wages he will perhaps be only credited with _three_ work hours, in other words the product value of three work hours will be assigned to him"; for the product value of one work hour would represent perhaps his contribution to the necessities of the State (taxes), and three work hours would have to go towards what is now called ground rent, and another three to interest on capital.
