Mandelson is no more a socialist than the average grabby little 18 month old child. He wants what you have and he wants more than you have, in fact as long as he is rich he doesn't give a hoot if you eat ants.(although no one is making a penny out of ant eaters)
As for McRipOff and the sustainability question in regards health, environment and growth it is a question of creating a need that otherwise may not have existed before and then profiting from it, which is something that capitalism thrives on.
"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."
Grunrisse, chapter 1 Production & Consumption.
Production and consumption are dependent upon each other, consumption is also a constituent of production and vice versa. This illustrates how need is met and at the same time stimulated, this is something that is not particular to capitalism but it is the mechanism whereby our mode of production creates needs otherwise not known/otherwise not commercial.
This explains quite clearly many things such as the market in creating insecurity in women and flogging the beauty myth for money and the fact that now plastic surgery is becoming the norm rather than the exception. The pervasive porn culture we live in creates a new market in dealing with peoples insecurities, it creates a need, the need goes unmet, it creates a product to meet the need it has created. The same is seen with most forms of welfare including treatments for obesity/diabetes.
