The wonder of the performance is the greater because of the odds against which it has been achieved. The stream of immigrants which has poured in is so large and heterogeneous that under conditions which formerly obtained it would have disrupted any semblance of unity as surely as the migratory invasion of alien hordes once upset the social equilibrium of the European continent. No deliberately adopted measures could have accomplished what has actually happened. Mechanical forces have operated, and it is no cause for surprise if the effect is more mechanical than vital. The reception of new elements of population in large number from heterogeneous peoples, often hostile to one another at home, and the welding them into even an outward show of unity is an extraordinary feat. In many respects, the consolidation has occurred so rapidly and ruthlessly that much of value has been lost which different peoples might have contributed. The creation of political unity has also promoted social and intellectual uniformity, a standardization favorable to mediocrity. Opinion has been regimented as well as outward behavior. The temper and flavor of the pioneer have evaporated with extraordinary rapidity; their precipitate, as is often noted, is apparent only in the wild-west romance and the movie. What Bagehot called the cake of custom formed with increasing acceleration, and the cake is too often flat and soggy. Mass production is not confined to the factory. The resulting political integration has confounded the expectations of earlier critics of popular government as much as it must surprise its early backers if they are gazing from on high upon the present scene. The critics predicted disintegration, instability. They foresaw the new society falling apart, dissolving into mutually repellent animated grains of sand. They, too, took seriously the theory of “Individualism” as the basis of democratic government. A stratification of society into immemorial classes within which each person performed his stated duties according to his fixed position seemed to them the only warrant of stability. They had no faith that human beings released from the pressure of this system could hold together in any unity. Hence they prophesied a flux of governmental régimes, as individuals formed factions, seized power, and then lost it as some newly improvised faction proved stronger. Had the facts conformed to the theory of Individualism, they would doubtless have been right. But, like the authors of the theory, they ignored the technological forces making for consolidation.
