The Labor Theory, upon which the entire proposition that working with capital ownerd by another is exploitation, is a dubious economic theory. Ive seen it used time and time again to 'explain' exploitation and it really ruins a socialists a arguments when scrutinised. This is a paraphrased text.
Karl Marx’s labor theory of value asserts that the value of an object is solely a result of the labor expended to produce it.
According to this theory, the more labor or labor time that goes into an object, the more it is worth. Marx defined value as
"consumed labor time", and stated that "all goods, considered economically, are only the product of labor and cost nothing except labor".
The labor theory of value is the fundamental premise of Marx’s economics and the basis of his analysis of the free market. If it is correct, then much of Marx’s critique of capitalism is also correct. But if it is false, virtually all of Marx’s economic theory is wrong.
Here is an example of how the labor theory of value works: A worker in a factory is given $30 worth of material, and after
working 3 hours producing a good, and using $10 worth of fuel to run a machine, he creates a product which is sold for $100. According the Marx, the labor and only the labor of the worker increased the value of the natural materials to $100. The worker is thus justly entitled to a $60 payment, or $20 per hour.
If the worker is employed by a factory owner who pays him only $15 per hour, according to Marx the $5 per hour the factory owner receives is simply a ripoff. The factory owner has done nothing to earn the money and the $5 per hour he receives is "surplus value", representing exploitation of the worker. Even the tools which the factory owner provided were, according to Marx, necessarily produced by other workers.
According to the labor theory of value, all profits are the rightful earnings of the workers, and when they are kept from the
workers by capitalists, workers are simply being robbed. On the basis of this theory, Marx called for the elimination of profits, for workers to seize factories and for the overthrow of the "tyranny" of capitalism. His call to action has been heeded in many countries throughout the world.
There are two fundamentally different answers to the question of where economic value originates. According to intrinsic theories of value, value is inherent in objects; remains constant despite changing demand, the passage of time, and other factors; and can be "objectively determined" by calculations based upon some fundamental scientific principle. The labor theory of value is clearly an intrinsic-value theory.
The other approach is the market-exchange theory. According to this theory, value is not inherent in objects, but is a product of many different consumer judgments. According to market-exchange theories, value depends upon people’s desires: the more they esteem an object and are willing to trade for it, the more it is worth. This theory is the basis of free-market capitalism, which Marx bitterly opposed.
At first glance, both theories seem to make sense. It is generally true that the more labor invested in an object, the more it is worth; but it is also true that the more people want something regardless of how much or how little labor went into it – the more it is worth.
Which theory is correct? Both of them cannot be, since they lead to diametrically opposite economic systems. The labor theory is flawed in that it considers labor to be the cause of value - it is not. The value is derived from the valuing.
The assertion that labor is the sole determinant of value is hard to accept just based upon common sense and experience. The assertion that only labor gives an object value ignores the fact that many natural objects in which no labor has been invested – such as scenic views, pure water, gems and minerals, and wild fruits and vegetables – have economic value. Also the labor theory cannot by its nature account for the fact that people value some natural objects, such as diamonds, tremendously more than other natural objects, such as leaves.
The labor theory of value also fails to take into account changing consumer desires and the contextual nature of value. In a
horse-and-buggy culture, horse-shoes are tremendously valuable commodities, but in a society without horses they are virtually useless. Similarly in a society with much leisure time, games and recreational facilities become important, but in a subsistence economy in which people must work nearly continuously just to stay alive, such things may actually have negative value.
The labor theory also ignores the importance of time and position. A 20-year-old wine is far more enjoyable than one-year-old wine. Oil in a desert is a potentially valuable resource, but oil in the local reservoir or in the middle of a farmer's field is a hazard.
Perhaps the most grievous theoretical fault with the labor theory is that it ignores what economists call time preference. Time preference is the common strong preference for goods and services here and now, rather than later. Present consumption is more valuable than future consumption.
For example, most workers prefer to be paid when their work is completed rather than when their products are sold – which may be months later. For workers to be paid now, rather than later, someone must advance their wages, and clearly this service has a value. But proponents of the labor theory would have it both ways: workers are to receive the full future value of their product now. In other words our wine worker would be demanding the full value of the wine ten years before it is bought.
The final theoretical failure of the labor theory of value is the value-effort fallacy. It is folly to assume that all effort produces value. Every day each of us wastes time on fruitless efforts. To equate labor with the automatic creation of value is to fallaciously imply that all human effort is infallible and constantly (and equally) productive.
The labor theory is even more absurd in practice. If all value is derived from labor, and entrepreneurial effort is "parasitic", who would bother to invest the time and money necessary to build factories, plan product development or organize a production process? If all profits are "exploitation", what incentive does anyone have to risk resource on a new and untried product or service? Where will the resource come from to finance new investment in tools?
Communist countries,as we have said before, have not abolished profits. They have merely transferred all profits to the state, which typically uses them to build a huge military apparatus at the expense of consumer production.
The labor theory of value is violently anti-consumer by its nature. Under this theory, sellers are compelled to price all goods by the amount of labor that goes into them, rather than how much they are demanded by consumers. Thus stores could charge no more for an aged foreign wine than for a local cheap wine (given equal labor input) or more for the work hacked out by a beginner. This inevitably produces a surplus of unskilled and shoddy work, and a shortage of skilled work, because doing something better that does not involve more sheer time-effort produces no more gain for a worker.
The labor theory also means the end of all economic freedom. Engels, Marx’s disciple, wrote: "For a pure Marxist society to long endure, voluntary exchange between individuals must be abolished." In a communist society you produce what the rulers tell you (and it doesnt matter if those rulers are the state or your fellows 'votes').
The most interesting fallacies of the labor theory of value are methodological. Labor theory arose from two extremely poor
methods of economic research. First it attempted to establish economic laws of exchange by examining only supply – ignoring demand entirely.
Even worse, the entire labor theory is unproven. In the entire first volume of Das Capital, where Marx proposed the labor theory, there is not one "positive proof". Rather Marx offers a fallacious "negative proof" in which he argues:
Premise 1 – some factor in the production of a good gives it value [true];
Premise 2 – only those goods to which man has applied labor have value [false];
Procedure – Examine all the factors producing a good by discarding those which did not create equal value in equal quantity, and end up with one factor – Labor. [Arbitrary].
Conclusion: Labor must be the source of value [False].
Marx promised to provide a positive proof in the Volume 3 of Das Capital. However, that book does not offer a positive proof, and implicitly refutes one. Marx proclaims that two types of capital exist in production, only one of which can produce "surplus value". Thus exchange of items of equal value can have uneven mixtures of these two types of capital, implying that labor alone is not the sole determinant of value.
The labor theory of value is nonsense both in theory and practice. It ignores the many non-labor factors which create economic value, is based upon unproved assertions, and leads to economic chaos and political slavery.
If you want to argue why making a profit is bad then do not do so from the labor theory of value - its a false premise and really ruins a socialists criticisms. Any other examples of anti-profit arguments would be welcome.
