On every hand we hear that the quality of immigration is not what it used to be. This is unwisely construed as meaning that we must withdraw our faith in mankind and raise rigid barriers always. Such a confession would declare the weakness of our institutions and undermine our faith in the principles on which the government is founded. The continuance of our faith is not interrupted by our intense conviction that there is no room in our midst for those whose direct purpose is political, social, or economic mischief, and whose presence jeopardizes the physical or moral health of the community. Certain laws of supply and demand take care, in normal times, of the coming and going of the alien. But it may be that today conditions abroad are so intolerable that men and women run chances in coming over without knowing the actual conditions they must face. Wise immigration laws would deal with such a pressure.
