At the risk of repeating some

At the risk of repeating some that has been said above…In capitalist society workers, in acting on the materials provided by nature produce all the wealth of society, yet not all workers actually produce ‘value’.It gets rather technical here, some sectors do not directly produce ‘value’ but siphon it off from other value producing sectors. This is not to say that the labour of non-value producing sectors is useful (though some of it may only be useful in the context of a capitalist system). In common usage the word ‘value’ means something different than it does in the Marxian sense.It is also worth noting that (intrinsic) ‘value’ and ‘exchange-value’ are not the same thing. To also further complicate things, as far as I know Marx did not use the term ‘labour theory of value’ to describe his theory, the labour theory of value really belongs to Smith and Ricardo. Some people think that Marx’s theory implies that commodities exchange at their ‘value’ equivalents according to necessary labour time, in fact this is what Ricardo not Marx claimed.If I’ve got it right Marx’s theory would not hold IF commodities exchange at value, in a capitalist society they generally exchange at price of production + average rate of profit, which is what Marx said. Marx’s theory is more to do with how labour is regulated in an economy governed by the law of value.Wealth and value are not the same thing, like as has been said a non-market economy would be governed by need, not socially necessary labour time.Clear?
