Dave, Mike,
Here's how it seems to me - the truck driver who carries goods from a factory to a store costs the employer something, that labor cost is part of the cost paid by consumers. Insofar as the wages of the truck driver equal the full cost of transport paid by consumers, then the truck driver isn't productive and isn't exploited (ie, they don't produce surplus value). If the shipping bill is higher than wages, then the truck driver is producing surplus value and is exploited. (More on this in a sec.) If the truck driver works for a shipping form to which shipping is outsourced, then the truck driver most certainly does produce surplus value and is exploited, as the firm bills the factory/store more for the shipping than it costs them to ship the goods. Otherwise the shipping firm would close. Right?
Mike, all of this I think hold by analogy with advertising. I'm leaving out 'in-house' advertising, only talking about outsourced advertising, in which case admakers produce surplus value and are exploited in that sense. I just checked the earlier thread and realized this has wandered from whether or not advertising is analogous to shipping (ie, if ad makers add value to the commodities they advertise), I'm going to have to bracket that for the meantime. For now I'm just interested in whether nonphysical commodities (conceptions about commodities, as you put it) can bear labor time in them, ie, if their production can be productive of surplus value. I don't care much about the issue beyond theoretical clarity, but I think they can. I'll try to chase up Marx's remarks on clowns and novelists are productive workers when I get time.
Back to the trucking example, it's not clear to me how surplus value is calculable within a firm, within a division of labor such that circulation work isn't value productive. How is surplus value production measured across departments? I worked in a small light industrial factory for a while, building big old trusses for the floors and roofs of buildings out of wood. Some guys cut the wood. Others assembled them on the line and guided them through a press machine to press plates into the joints to hold them together, others flipped them over and put plates on the other side and guided them through the next set of rollers, then they got stood up on racks in the yard for a forklift operator to put them on a truck. Who in that series produces surplus value at what rate? By position, I mean. It seems to me that surplus value is distributed across the shopfloor, surplus value made by the capitalist is the product of the workers there working as an ensemble. If the total surplus of the plant is, say, $120k a month and there's 50 guys (including the forklift operators and truckers) making an average of $2k a month each, surplus value is $20k, $400 each on average. It seems to me that this includes the forklift operators and truckers, because their work is integral to the recouping of value advanced (if the trusses don't get loaded and shipped then value advanced can't come back, surplus can't be realized). Am I making a mistake someplace? If so, where? If not, then what if this wasn't a truss factory but was an ad agency, with bike couriers and office mail guys instead of truckers and forklift drivers. I don't see what changes, other than that ads have a stupider use value than trusses.
) - these are all part of the cost of production (accounted for or otherwise). Wages are also determined by the strength of the truck drivers, not to mention the variations in gas prices - you can't 'calculate' surplus value out of monetary amounts.




Can comment on articles and discussions
I can accept this insofar as advertisments are themselves sold as commodities. Nevertheless, their value is negligible given the fact that the labor that goes into originally producing the ad is rapidly devalued to the cost of the materials on which the ads are printed. (For example, the cost of paper and printing, and close to zero in the case of electronic ads.)
Of course, ads do help individual firms acquire extra profit by drawing demand away from competition. But there is a difference between the acquisition of profit and the production of surplus-value.
