For the moment, we are not concerned with the prediction that Socialism must follow the full development of capitalism. The important point for our present study is the predicted growth of monopoly out of competition, and the manner in which that prediction has been realized. Concerning the manner and extent of the fulfillment of this prediction, there have been many keen controversies, both within and without the ranks of the followers of Marx. While Marx and Engels are properly regarded as the first scientific Socialists, having been the first to postulate Socialism as the outcome of evolution, and to explore the laws of that evolution, they were not wholly free from the failings of the Utopists. It would be unreasonable to expect them to be absolutely free from the spirit of their age and their associates. There is, doubtless, something Utopian in the very mechanical conception of capitalist concentration which Marx held; the process is too simple and sweeping, the revolution too imminent. Still, by followers and critics alike, it is generally conceded that the _control_ of the means of production is being concentrated into the hands of small and ever smaller groups of capitalists. In recent years the increase in the number of industrial establishments has not kept pace with the increase in the number of workers employed, the increase of capital, or the value of the products manufactured. Not only do we find small groups of men controlling certain industries, but a selective process is clearly observable, giving to the same groups of men control of various industries otherwise utterly unrelated.
