measure due to economic causes. It should be stated, however, that
emigration from Europe is not now an absolute economic necessity, and as a
rule those who emigrate to the United States are impelled by a desire for
betterment rather than by the necessity of escaping intolerable
conditions. This fact should largely modify the natural incentive to treat
the immigration movement from the standpoint of sentiment, and permit its
consideration primarily as an economic problem. In other words, the
economic and social welfare of the United States should now ordinarily be
the determining factor in the immigration policy of the Government."

This delimitation of the immigration problem to its economic aspects led
the Immigration Commission to recommend a somewhat restrictionist policy.
That they were not without warrant in so delimiting it is evident from the
utterances of such ardent opponents of restriction as Dr. Peter Roberts
and Max J. Kohler. The latter, writing in the _American Economic Review_
(March, 1912) said: "In fact, the immigrant laborer is indispensable to
our economic progress today, and we can rely upon no one else to build our
houses, railroads and subways, and mine our ores for us." Dr. Roberts'
plea is almost identical.

What a glaring misconception of the whole economic and social problem is
here involved will appear if we add a clause or two to Mr. Kohler's
sentence. He should have said: "We can rely upon no one else to build our
houses, railroads and subways, and mine our ores for us _at $455 a year;
for workers of native birth but of foreign fathers would cost us $566, and
native born White Americans $666 a year_." (See Abstracts of Rep. of
Immigr. Comm. vol. i., pp. 405-8.) These are the facts. This is the social
situation as it should be stated if a candid discussion of the problem is
sought.
