QUOTE : As holders of money, labourers are free to buy as they please, and they have to be treated as consumers with autonomous tastes and preferences. We should not make light of this (Grundrisse, p. 283). Situations frequently arise in which labourers can and do exercise choice, and the manner in which they do so has important implications. And even if, as is usually the case, they are locked into buying only those commodities capitalists are prepared to sell, at prices capitalists dictate, the illusion of freedom of choice in the market plays a very important ideological role. It provides fertile soil for theories of consumer sovereignty as well as for that particular interpretation of poverty that puts the blame fairly and squarely upon the victim for failure to budget for survival properly. There are, in addition, abundant opportunities here for various secondary forms of exploitation (landlords, retail merchants, savings institutions), which may again divert attention from what Marx considered to be the central form of exploitation in production.
