There are some who believe that it would be wise to prohibit immigration altogether, at any rate until conditions in both Europe and America become more settled. They argue that we already have as many aliens as we can Americanize for some time; that immigration at the present time increases unemployment, and that the quality of immigrants is now considerably below what it used to be. On the other hand it is urged that the industrial growth of the United States requires a larger supply of labor than can be provided without immigration and that by providing proper facilities for selection we can make sure of getting only the right type of immigrant. =Our Racial Problems.=—We have several serious racial problems in this country including the problem of the European immigrants in the East (particularly in the cities), the negroes in the South, and the Japanese on the Pacific slope. The large percentage of European immigrants in the Eastern cities has already been mentioned, and the problems which their presence in these cities creates have been alluded to. The European immigrant can be assimilated, but the process takes time because a large part of it must be accomplished through education. If the immigrants could be persuaded to scatter over the country instead of congregating in the cities with their fellow-immigrants, the problem of making real Americans out of them in a short time would be simplified. [Sidenote: Extent of the negro population.] =The Negroes.=—The problem of the negro is older and more difficult still. They are of a race so far removed from the white population of the United States that there is no hope of their ever being assimilated. They were brought here by the tens of thousands without any adequate appreciation of the problem which their presence would eventually create, and they form an unmeltable mass in the melting-pot of American society. At the outbreak of the Civil War the colored population of the United States, most of whom were then slaves, numbered less than five millions, or about one-tenth of the total population of the entire country. Now they number about ten millions. In other words the negroes have a little more than doubled in sixty years. This is a much slower rate of natural increase than has been made during the same sixty years by the white population. A high death rate, especially in the cities, is mainly responsible for this.
