[167] It must be borne in mind that many articles of utility and enjoyment must in their final processes be produced for immediate consumption. The "saving" of perishable goods is confined to a saving of the more enduring forms of machinery engaged in their production, or in some few cases to a storing up of the raw material. So likewise that large portion of productive work termed "personal services" cannot be antedated. These limits to the possibility of "saving" are important. No amount of present sacrifice in the interest of the next generation could enable them to live a life of luxurious idleness.
[168] Ruskin, Unto this Last, p. 145.
[169] This does not necessarily imply a stimulation of new saving. A fuller vitality given to existing forms of capital will raise the quantity of real capital as measured in money. Mills and machinery which have no present or future use, though they embody saving, have no value and do not increase real capital.
