All are constructed with a view to keeping the family group united, and each family group separate from all others.

Further, if the natural family propensities thus affect the structure of the dwelling, other propensities, more various in detail, but in each case equally spontaneous, determine what commodities shall be put into it.
And this fact brings us back to our own more immediate subject--namely, the power of the few and of the many in the sphere of economic production.

The man of exceptional industrial capacity becomes rich in the modern world by producing goods, or by rendering services, which others consume or profit by, and for which they render him a return.
But, in order that they may take, and render him this return for what he offers them, the goods and the services must be such that the many desire to have them.

All the highest productive ability that has ever been devoted to the business of cheapening and multiplying commodities, or rendering social services, would be absolutely futile unless these commodities and services satisfied tastes or wants existing in various sections of the community.

The eliciting of such wants or tastes depends very often, and in progressive communities usually, on a previous supply of the commodities or services that minister to them--as we see, for example, in the case of tobacco, of the telegraph, and of the bicycle; but, when once the demands have been elicited, they are essentially democratic in their nature.
