"And in like manner all who had pleasure to sell--the artists, the players, the singers, yes, and the courtesans also--flocked to the cities for the same reasons. And those who desired pleasure and had wealth to buy it, those who wished to enjoy life, either as to its coarse or refined gratifications, followed the pleasure-givers. And, finally, the thieves and robbers, and those pre-eminent in the wicked arts of living on their fellow-men, followed the throng to the cities, as offering them also the best field for their talents. And so the cities became great whirlpools, which drew to themselves all that was richest and best, and also everything that was vilest, in the whole land. "Such, Julian, was the law of the genesis and growth of the cities, and it was by necessary consequence the law of the shrinkage, decay, and death of the country and country life. It was only necessary that the era of private capitalism in America should last long enough for the rural districts to have been reduced to what they were in the days of the Roman Empire, and of every empire which achieved full development--namely, regions whence all who could escape had gone to seek their fortune in the cities, leaving only a population of serfs and overseers. "To do your contemporaries justice, they seemed themselves to realize that the swallowing up of the country by the city boded no good to civilization, and would apparently have been glad to find a cure for it, but they failed entirely to observe that, as it was a necessary effect of private capitalism, it could only be remedied by abolishing that." "Just how," said I, "did the abolition of private capitalism and the substitution of a nationalized economic system operate to stop the growth of the cities?" "By abolishing the need of markets for the exchange of labor and commodities," replied the doctor. "The facilities of exchange organized in the cities under the private capitalists were rendered wholly superfluous and impertinent by the national organization of production and distribution. The produce of the country was no longer handled by or distributed through the cities, except so far as produced or consumed there. The quality of goods furnished in all localities, and the measure of industrial service required of all, was the same. Economic equality having done away with rich and poor, the city ceased to be a place where greater luxury could be enjoyed or displayed than the country. The provision of employment and of maintenance on equal terms to all took away the advantages of locality as helps to livelihood. In a word, there was no longer any motive to lead a person to prefer city to country life, who did not like crowds for the sake of being crowded. Under these circumstances you will not find it strange that the growth of the cities ceased, and their depopulation began from the moment the effects of the Revolution became apparent." "But you have cities yet!" I exclaimed.
