(5) The extent to which the immigration movement of the present is a stimulated one has already been indicated. It might seem at first that it made no difference to the United States whether the immigrant was induced to come, or whether he came of his own volition. But a closer consideration shows that there is a fundamental difference. A strictly natural immigration would mean that immigrants came in response to some actual economic demand in this country which was strong enough to make itself felt abroad. They would also be the ones best fitted to meet that demand. But when one of the greatest motives back of immigration is the desire of the transportation companies to make money, the mere fact of emigration is no indication of any real need for the immigrant in this country, nor of his fitness to enter into its life. (6) Owing to the very strict wording of our contract labor law, a very large proportion of our immigrants enter the country under the impression, either false or correct, that they are evading the law. This has a very serious effect upon their character, and upon their attitude toward American institutions. They may readily conceive that a country that has such laws that it is necessary to break them to get in, probably has other laws that need to be broken after one is in. The whole system engenders a most dangerous attitude of indifference or hostility to law. (7) The biological argument of the restrictionist is the obverse of the biological argument of the pro-immigrationist, and is equally vague in the present state of our knowledge on the subject of race mixing. Those who urge this argument against immigration are those who believe that only when the mingled races are closely allied is the resulting stock of a superior type, or else those who hold the extreme view that no mixed race is as good as a pure race. At any event, they believe that the racial elements which are now coming to the United States are too diverse to produce anything but an inferior stock through their interbreeding. In this connection it should be observed that there are two possible results of this gathering of races in the United States, each with its own problems. One is that these races will, in the course of time, become so blended through intermarriage as to produce one composite but homogeneous whole—the new American people. The other is that race prejudice and the forces of segregation will result in the growth of a large number of ethnic groups within the nation, each with its own peculiarities, and each distinct from the others. There are some indications which point to the latter as the more probable outcome.[352]
