«All contemporary ‘developed’ societies, including ‘socialists’ ones, depend on the unpaid labour of women for domestic services and child-rearing. The services are furnished within the framework of a particular relationship to an individual (the husband). They are from the realm of exchange and consequently have no value. They are unpaid. Whatever women receive in return is independent of the work which they perform because it is not handed out in exchange for that work (i.e. as a wage to which their work entitles them), but rather as a gift. The husband’s only obligation, which is obviously in his own interest, is to provide for his wife’s basics needs, in other words, he maintains her labour power.»
