I don't know if anyone can post answers in this "ask a...", but as the thread seems anarchic

already, I want to answer a previous post:
I'm not talking about overproduction. I'm talking about the lack of overproduction. Marx's idea of overproduction is tied to his adherence to Lassalle's Iron Law of Wages, that is, wages in the long run stay at the minimum amount that barely keeps the worker alive, so anything capitalism produces that're more than the absolute essentials (plus whatever luxuries the capitalists themselves can consume) are overproduced. In other words, capitalism produces more than what the working class could afford. It wasn't made clear whether or how capitalism can produce more than everyone's needs, or even wants, which are more relevant given that the Iron Law is proven wrong in modern times.
More relevant? How so? Under capitalism a company must only produce as much as its customers can afford. If it overproduced it ends up unsold, at a loss to the company. That's what nearly caused the bankruptcy of the major automakers (overproduction of automobiles). That's what nearly caused the bankruptcy of the major banks (overproduction of housing). Despite the fact that people still want more cars, despite the fact that people are still homeless, or in fact being evicted from houses when they cannot pay the mortgages.
Anyway, what do you mean by "his adherence to it"? Marx clearly saw that wages were negotiated in a political process. He encouraged that workers organize to defend their interest within that political process. And it paid: the iron law of wages was indeed wrong during the social-democrat experiment in capitalist countries. Since social democracy has been dumped, which would be the 1970s in the US and late 1980s in Western Europe, the labor share of wealth has been steadily reduced. I could give you the numbers, but there's one much better piece of evidence: the continuous rise of consumer debt. If the working class kept earning enough to consume the economic output of its work, it would not need to borrow. But it has bee borrowing, increasingly so. Obviously such a system is unstable and must end in an "overproduction crisis" followed by cuts on economic output and employment - the cyclic depressions of capitalism are back.
To illustrate this difference, consider again the iPhones. Suppose Steve Jobs sold iPhones in Britain in 1800. All he would need to reach overproduction were probably a few thousand handsets, given that only the aristocracy could afford it. These days, an average British worker can easily afford an iPhone. Overproduction would require many millions of the said phone. While a thousandfold increase in productivity is not impossible, you cannot assume it will always happen. As a matter of fact, Mr Jobs did not overproduce iPhones, which were notoriously undersupplied at the times of a new release.
Oh, please! Demand management, anyone?
It's a mathematical reasoning - not proof - of why your self-interest can make you "respect someone else's private property and other rights", and why "respecting private property and the laws that make our society cohesive" are in fact quite natural. You should read it.
Mathematical reasoning can be used to "prove" - you can deny it, but that was your intention -
anything. It all depends on your axioms. And it so happens that the "prisoner's dilemma" is not representative of all human experience. In fact I dare say that none of us posting here find ourselves in a "prisoner's dilemma" situation frequently.
It is very telling that you need to choose such specific, outlandish starting conditions (two criminals bargaining...) in order to "prove" selfishness to be good! It's a recurring feature of neoclassical economics: simplistic metaphors disguising unrealistically starting conditions, used as foundations for mathematical models which "prove" whatever is politically expedient.
Ironically, that's your usual complaint about marxism - that it has a political agenda and doesn't actually prove its claims. Well, I think that we can easily establish that, regarding those criticisms,
modern economics is in no way better. But Marx at least had the decency of actually recognizing that he was doing politics.
