Assisted immigration is the term used to cover cases where a foreign government has eased itself of part of the burden of its paupers, insane, dependents, and delinquents by shipping them to the United States. This was not uncommon in the nineteenth century, especially in the case of local and municipal governments. Our laws were lax, and for a time nearly everybody, sane or insane, sound or diseased, was passed. The financial gain to the exporting government can be seen in the fact that it costs about $150 per head a year to support dependents and delinquents in this country, while it would not cost the foreign authorities more than $50 to transport them hither. This policy seems scarcely credible, but Switzerland, Great Britain, and Ireland followed it thriftily until our laws put a stop to it, in large part, by returning these undesirable persons whence they came, at the expense of the steamship companies bringing them. It was not until 1882, however, that our government passed laws for self-protection, and in 1891 another law made "assisted" immigrants a special class not to be admitted. [Sidenote: Other Causes] Other and incidental causes there are, such as the influence of new machinery, opening the way for more unskilled labor, such as the ordinary immigrant has to sell; the protective tariff, which shuts out foreign goods and brings in the foreign producers of the excluded goods; the thorough advertising abroad of American advantages by boards of agriculture and railway companies interested in building up communities; and a fear of restrictive legislation. But undoubtedly, ever back of all other reasons is the conviction that America is the land of plenty and of liberty--a word which each interprets according to his light or his liking.
