_The Importance of Delay in the Closing of Marginal Establishments._--Now, this process looks as if, by the closing of mills that are distanced in the race of improvement, labor must be forced out of the subgroup. So it would be if the reducing of the price to its new static level were an instantaneous operation and the inferior mills were, in the same instantaneous fashion, compelled to close their doors. These, however, are gradual operations, and before they can possibly produce their full effects, influences will have been set working which will counteract the expelling tendency. We have cited as such an influence the general growth of society in numbers, wealth, and consuming power, making it possible for a group, when an economical change has taken place, to produce and sell more goods than before and to keep its accustomed force of labor in order to do so. There are certain more specific influences which have a similar effect and render it as unnecessary as it is useless to attempt to resist the course of improvement. _Centralization of Business an Effect of Progress._--From the facts here cited it appears that conservatism of the kind that resists all changes condemns an _entrepreneur_ to destruction. He must keep in a moving procession in order to survive. As the essential thing which is changing is the price-making cost of goods, the _entrepreneur_ must see to it that in his establishment cost declines. While this does not necessarily mean that every such establishment needs forever to grow larger, since there are local conditions in which relatively small shops may be economical enough to survive, yet those which cater to the general market and directly encounter the competition of the great producing establishments must, as a general rule, have the advantages of great size in their favor, or sooner or later be crowded out of the field. Many of the smaller ones fall by the wayside, and the business they have done passes to their already large rivals. Wherein the advantages of the great shop lie and how one that is of less than a maximum size may survive in spite of them, are points for later consideration.
