What was a common complaint of nativist groups in the US during the late 19th century and early 20th century?

Nativist groups in the US during the late 19th and early 20th centuries commonly complained about the influx of immigrants, particularly from Southern and Eastern Europe, fearing that these newcomers would undermine American culture, values, and job opportunities. They expressed concerns over perceived threats to social cohesion, national identity, and economic stability, often blaming immigrants for crime, poverty, and labor competition. This led to calls for stricter Immigration controls and the promotion of policies that favored native-born Americans.
