If the pecuniary situation of the master permits it, the development of a special class of personal or body servants is also furthered by the very grave importance which comes to attach to this personal service. The master's person, being the embodiment of worth and honour, is of the most serious consequence. Both for his reputable standing in the community and for his self-respect, it is a matter of moment that he should have at his call efficient specialised servants, whose attendance upon his person is not diverted from this their chief office by any by-occupation. These specialised servants are useful more for show than for service actually performed. In so far as they are not kept for exhibition simply, they afford gratification to their master chiefly in allowing scope to his propensity for dominance. It is true, the care of the continually increasing household apparatus may require added labour; but since the apparatus is commonly increased in order to serve as a means of good repute rather than as a means of comfort, this qualification is not of great weight. All these lines of utility are better served by a larger number of more highly specialised servants. There results, therefore, a constantly increasing differentiation and multiplication of domestic and body servants, along with a concomitant progressive exemption of such servants from productive labour. By virtue of their serving as evidence of ability to pay, the office of such domestics regularly tends to include continually fewer duties, and their service tends in the end to become nominal only. This is especially true of those servants who are in most immediate and obvious attendance upon their master. So that the utility of these comes to consist, in great part, in their conspicuous exemption from productive labour and in the evidence which this exemption affords of their master's wealth and power. After some considerable advance has been made in the practice of employing a special corps of servants for the performance of a conspicuous leisure in this manner, men begin to be preferred above women for services that bring them obtrusively into view. Men, especially lusty, personable fellows, such as footmen and other menials should be, are obviously more powerful and more expensive than women. They are better fitted for this work, as showing a larger waste of time and of human energy. Hence it comes about that in the economy of the leisure class the busy housewife of the early patriarchal days, with her retinue of hard-working handmaidens, presently gives place to the lady and the lackey.
