But I have to add one more point. If the repair is empolyed as a part-time
laborer, its wage is to be classed as a (fluid) constant capital, only if
the repair is not beyond the normal, average repair. But if the repair is
above the average, it should be a deduction from the surplus-value. On the
other hand, if he is employed as a full-time laborer, his wage should be
counted in the normal, regular production cost as a part of the variable
capital. He can then prevent the deduction from the surplus-value in case
that repairs occur above the average, normal cost, and, in addition, he can
save the capitalist's money (creating surplus-value) when the repair is done
below the average.
