Well, the decision isn't made arbitrarily. Marx is identifying a historical shift. Doctors operating on bodies, or diagnosing bodily ailments, is a tradition that precedes capitalism. He's interested in huge quantities of labor because that is the phenomenon as it emerges in late-18th/19th-century Europe.
.....
Given the process of industrial and technological development, I'd say it's a very substantial window.
By tiny I was referring to the limitation to a specific and limited segment of the economy in a specific time, while murky was specifically the requirement of abstracting out to the point where only a vague blob labeled "labour" is visible.
While he is interested in labour and commodities, I cannot find where he makes any compelling argument for LToV; he really just submits it in the first few pages, and begins building on it.
"What can be charged" is surplus value; it must go above and beyond the cost it took to produce the commodity. So, for Marxism, the very notion of subjective value (i.e. what people will pay for something) is bound to the problem of exploitation, because it allows the employer to rationalize charging beyond what it cost to make the item.
What can be charged might also be less than cost. Then x commodity doesn't get made. To state that something like surplus value (of course referring to value in exchange terms) exists requires first that some sort of objective exchange value exists. If it is merely the cost of production, doesn't raising costs negate "surplus"? This is what "non-profits" do. But even if the "business" doesn't profit, people do. I just worked two overnights. I considered the pay more valuable than all my other available options. I don't
need the money to survive, but it makes other things easier - I offered a service in exchange for promise of future services (commodities do function as service also). Therefore, I profited. Other employees, as well as the company, profited or benefited from having shelves better prepped for inventory. This is Bastiat's exchange of services.
What is the hourly value of moving heavy objects and operating power equipment. I'm sure many people get paid minimum wage for that. I get paid over minimum wage. Am I exploiting my employer by charging more for my labour than what it should cost?
If you believe axiomatically that people should work for their possessions, then it makes sense to believe wholeheartedly in free-market economics. If you believe that cornering a niche in the market and charging people extra for it is parasitic, then it makes sense to believe wholeheartedly in Marxist critiques of economic behavior.
I don't agree that people should (as in have to) work for their possessions in all cases (what about gifts?), and I do believe cornering markets
in some ways is parasitic (for instance, rent seeking, special privilege in the forms of license etc). But Marxism doesn't really address the latter, while he explicitly acknowledges that people do work for possessions - or at least some do anyway.
Free market economics is not based axiomatically on "people should have to work for their possessions". It is based on the individual ownership of self. Ownership of self includes ownership of actions and products, and ownership of product includes the ability to exchange.
So now you're saying that price equals value? But as we've said earlier (I thought), price doesn't equal value. We can only use price as a signifier of value if we take into consideration products entirely on the same level. I'm not arbitrarily disregarding time left sitting on a coat rack; I'm saying that once we take cultural exposure into consideration it doesn't make sense to equate price with value. Marx might very well say that the price difference in this case is merely another example of exploitation, since the employer is still bagging surplus costs despite the dwindling amount paid to the laborer. Theoretically, in this case, if the coat sits that long on the rack, the laborer should receive the amount promised for the coat while the employer sacrifices his surplus value since (obviously) he/she misjudged what could be charged beyond the cost of production.
I'm not sure why using price is confusing. Marx specifically does this. I even use Coats and Linen in Form B. Price is exchange value, and in Moneyed-form, or "Form C", is in currency units rather than commodity.
Other than commission arrangements, I don't know of any situation where laborers receive wages only upon sales of commodities. When I go to work, I'm not hoping enough people by plywood that day or whatever. How the laborer is getting shafted in the coat scenario is beyond me, particularly in the case of the older coat. I sell my labor for x amount an hour to a retail store. The store sells most items at a profit, but in many cases it does not. Stores can sell for less than cost for three reasons:
Clearance and/or Damage (like in the coat example)
"Loss-leaders" - a markdown on a high profile item to drive traffic, hoping to recoup the losses on that item with profits on others.
"Predatory markdowns" or however they are called, where a large chain opens a new location and sets prices below area competitor prices at a loss, hoping the competition goes out of business and then prices can be raised (perhaps even higher than the competition was).
If I work for a store engaged in any of the above (and my workplace does the first two quite often enough, particularly markdowns on damaged goods), I don't have to worry about my paycheck reflecting. Hell, in the process of moving building supplies around with power equipment, things get dinged and nicked fairly often, sometimes to the point of needing to be marked down. Even if responsible, it doesn't come out of my paycheck, it comes out of the bottom line of the company.
Assuming and managing the risks of business would be asinine without the potential of profiting. You suggested that in the case of the coat markdown, the employer should assume the loss - this is exactly what happens in business as it stands. But how is it fair an employer assumes all losses but no gains? How would such a model even work?
I agree that Marx is dismissive of Bastiat; but I don't think it's because he isn't familiar with Bastiat's work. Just glancing at his short essay "Bastiat and Carey" shows that he's read the former; but I believe he finds Bastiat tedious. Depending on where one's values lie, I don't see how either could stand the other for very long.
Bastiat even apologizes for his redundancy, so to call him tedious on some things isn't unfair (When he uses reducto ad absurdum/satire constitutes his most engaging reading.) In fact, his chapter on Value might be one of the worst cases of redundancy. But yeah, Marx called Free Marketers "bag men", and I'm pretty sure Bastiat would consider Marx something worse.
Marx isn't concerned with why people want anything either. The concern is how people represent "want" to themselves. The commodity (e.g. "diamonds") is a social hieroglyphic that reorganizes relations between people, who can "want" diamonds for any reason. But this reason is partially conditioned by the hieroglyphic itself, meaning it contributes to how people "want" it.
Diamonds are a good example.
Q: Why are diamonds expensive?
A: Because people want diamonds.
Q: Why do people want diamonds?
A: Because they're expensive.
Diamonds are actually an extreme example, but the same logic works internally with any commodity. Obviously someone wants a coat to keep warm; but someone wants a Neiman Marcus coat because it's a Neiman Marcus. The point here isn't to qualify why people want something; it's to demonstrate that the logic of "want" can be orchestrated or perpetuated in large part by a producer, rather than totally by the practical use-value of a commodity.
This area is interesting, but doesn't require analysis of economics nor depend on LToV to move forward. If he had stuck with only this hundreds of millions might not have died. Minimalists are pretty harmless folks.
I certainly agree there are times where ownership becomes the "need" itself (which is what I just assumed was meant by Fetishism; as Marx opens on it, I see this might not be the case). "I want it because - I simply want to have it". Wanting a given name brand though does not necessarily reflect this. Social gains, or wanting a particular quality in construction, etc can play a roll. While any car at any given time might be capable of getting me from point A to B, I prefer to buy Hondas for the general quality. Although not necessarily intended for this illustration by Tolkien, Gollum is a good example of my conception of the Fetishization of Commodities.
How is labor destroyed? I doubt the laborer feels as though her labor was destroyed.
Lets say I build a house, and it is so poorly made that it immediately falls down. My labor was destroyed. Now this is a rather extreme and absurd example, but it is same if I labor in any other poor or unwanted way.
I'm uncertain how this relates to everything else.
This is another thing refuting a direct
labor-input = value relation.
While an aside to all that, it also relates as a crazy coincidence (and I swear this kind of coincidence has happened before): Mises.org just ran an article explaining the difference between Mengerian Marginalism and the other Marginalists. They also ran another article on libertarian literary critique. A welcome change for something interesting, the site had been rather dry lately.
