According to the established laws of economics there are two ways in which immigration may operate to lower wages. First, by increasing the supply of labor in the country, and thereby diminishing the amount of remuneration which the individual laborer can command. Second, by introducing a body of laborers whose customary wage in the countries they come from, and whose corresponding standard of living, is much lower than the prevailing standard in the new country. This factor operates, not by increasing the number of laborers bidding for employment, but by lowering the amount of the initial bid on the part of a sufficient number of laborers to fix the remuneration for the whole lot. As to the first of these ways, if the argument contained in Chapter XI is valid, it is not probable that in the long run immigration has materially increased the total population of the United States. But it has, from time to time, caused a marked temporary increase in the body of unskilled labor, and this, as will be shown later, is an important matter. However this may be, the second of these two ways has undoubtedly been by far the more instrumental in reducing the average wage of the American workman. It is not because he has had to compete with more laborers, so much as with cheaper laborers, that the American workman has failed to secure a higher remuneration for his services. It is what Professor Commons has called the “competitive struggle for standards of living”[270] which has been the determining factor, and the whole matter can be best understood by taking it up in the light of the general standard of living, rather than of mere wages.
