How did immigration help American industries grow?

Immigrants were generally more willing to accept lower wages and inferior working conditions than native born workers (Zolberg 2006: 69). Great efficiencies in production led to higher profits that could be reinvested in new technology, which led to even more production and eventually higher wages for workers.

The researchers believe the late 19th and early 20th century immigrants stimulated growth because they were complementary to the needs of local economies at that time. Low-skilled newcomers were supplied labor for industrialization, and higher-skilled arrivals helped spur innovations in agriculture and manufacturing.
