Marx describing how production (in general) creates demand. Consumption and Production as instantaneously equal.

From the introduction of Grundrisse

Text:

Production, for its part, correspondingly (1) furnishes the material and the object for consumption. [15] Consumption without an object is not consumption; therefore, in this respect, production creates, produces consumption. (2) But the object is not the only thing which production creates for consumption. Production also gives consumption its specificity, its character, its finish. Just as consumption gave the product its finish as product, so does production give finish to consumption. Firstly, the object is not an object in general, but a specific object which must be consumed in a specific manner, to be mediated in its turn by production itself. Hunger is hunger, but the hunger gratified by cooked meat eaten with a knife and fork is a different hunger from that which bolts down raw meat with the aid of hand, nail and tooth. Production thus produces not only the object but also the manner of consumption, not only objectively but also subjectively. Production thus creates the consumer. (3) Production not only supplies a material for the need, but it also supplies a need for the material. As soon as consumption emerges from its initial state of natural crudity and immediacy – and, if it remained at that stage, this would be because production itself had been arrested there – it becomes itself mediated as a drive by the object. The need which consumption feels for the object is created by the perception of it. The object of art – like every other product – creates a public which is sensitive to art and enjoys beauty. Production thus not only creates an object for the subject, but also a subject for the object. Thus production produces consumption (1) by creating the material for it; (2) by determining the manner of consumption; and (3) by creating the products, initially posited by it as objects, in the form of a need felt by the consumer. It thus produces the object of consumption, the manner of consumption and the motive of consumption. Consumption likewise produces the producer’s inclination by beckoning to him as an aim-determining need.
