The household has been treated by economists with curious negligence. The founder of political economy showed so little insight into the real nature of the work carried on there as to class those whom he described as menial servants with unproductive labourers.[13] The later classical economists have followed his lead. Marshall, it is true, shows throughout his books an appreciation of the position and responsibilities of the housewife and the mother which is foreign to most of his colleagues.[14] But he has never attempted to analyse the economic functions of the household, or to show its varying relations to the rest of the community; neither has he pointed out the peculiar factors which differentiate the position and remuneration of the women employed in domestic activities from those of all other workers. On the other hand, the more modern school of economists, those who devote themselves to the history of economic development in the past or to the intensive study of special economic institutions in the present, have equally failed to discuss with any adequacy the organisation of the household. The economic historians describe with minuteness the rise and fall of gilds and chartered companies, the workings of different methods of education and of poor relief in successive epochs. They rarely indicate how the various forms of industrial organisation translated themselves into the domestic expenditure of the people. It would, for instance, be very difficult to extract from the pages of the economic historians an answer to the question, "What were the conditions determining the supply of domestic servants at the close of the Middle Ages, in the eighteenth century and in the nineteenth century respectively?" It is not easy to answer definitely even simpler and more fundamental questions than these. It is often stated, for example, that the household arrangements of the serfs on the mediæval manors were rude and uncomfortable to the last degree,[15] but it is certain that this is not so universally true as has been thought. Some at all events of the more prosperous inhabitants of the manors possessed household furniture and equipments of a kind not inferior to the outfit of the casual labourer to-day. Sheets, for example, are mentioned several times in extant inventories. But much more investigation than has yet been possible would be necessary before it could be determined whether these instances of a higher standard of comfort are or are not exceptions to a general rule.
