[...] the most far-reaching and significant of Marx's assumptions concerns the unchallenged power of private property rights in both production and exchange. It is in this context that he also assumes perfect competition in the market place. He accepts Adam Smith's theory of 'the hidden hand' although he insists that the hidden hand is that of labour not that of capital. Monopoly power is assumed away. Why he adopted these assumptions is an interesting question. My guess is that Marx's primary intent in Capital is to deconstruct the utopian vision of free market capitalism that the political economists of the time were promoting.

money is more geographically mobile than commodities and both are much more geographically mobile than production This has important implications for understanding the role of financialisation in globalisation.

[...] we know from the analysis of the circulation of capital that a great deal of appropriation of value through predation occurs at the point of realisation. Increasing the minimum wage or creating a basic income will amount to naught if hedge funds buy up foreclosed houses and pharmaceutical patents and raised prices (in some cases astronomically) to line their own pockets out of the increased effective demand exercised by the population. Increasing college tuitions, usurious interest rates on credit cards, all sorts of hidden charges on telephone bills and medical insurance could steal away all the benefits. A population might be better served by strict regulatory intervention to control these living expenses, to limit the vast amount of wealth appropriation occurring at the point of realisation. [...]
