Marx rejects as absurd the contention made by John Stuart Mill, and many of the political economists, that while production is governed by definite laws, distribution is controlled by (malleable) human institutions. Such a view underlies the assumption that classes are merely inequalities in the distribution of income, and therefore that class conflict can be alleviated or even eliminated altogether by the introduction of measures which minimize discrepancies between incomes.
