What was the impact of global migration on the United States during the 1800s and early 1900s?

From 1850 to 1930, the foreign born population of the
United States increased from 2.2 million to 14.2 million.  This particular and singular
fact might help to explain the impact of global migration on the United States.  At the
time, the wave of industrialization was sweeping through the nation.  The emergence of
over 10 million immigrants helped to provide a ready labor pool for these industrialists
who had centralized their factories in urban settings.  This helped to increase the
generation of business in America in the late 19th and early 20th Centuries.  It is
through this growth of industry where one sees the greatest impact on global migration
in America of the time period.  As immigration increased, there was a correlative issue
of affordability in emigrating to the United States.  From 1880 to 1924, over 25 million
Europeans migrated to the United States, helping to confirm this assertion.  This also
helps to underscore the impact of global migration in America of the late 1800s and
early 1900s.
