Page "Socially necessary labour time" Paragraph 24
" All that palaver about the necessity of proving the concept of value comes from complete ignorance both of the subject dealt with and of scientific method.
Every child knows that a nation which ceased to work, I will not say for a year, but even for a week, would perish.
Every child knows, too, that the masses of products corresponding to different needs require different and quantitatively determined masses of the total labour of society.
That this necessity of the distribution of social labour in definite proportions cannot possibly be done away with by a particular form of social production but can only change the mode of its appearance, is self-evident.
What can change in historically different circumstances is only the form in which these laws assert themselves.
And the form in which this proportional distribution of labour asserts itself, in a state of society where the interconnection of social labour is manifested in the private exchange of the individual products of labour, is precisely the exchange value of these products.
