Question

Can you predict how later groups of immigrants, like the Italians, the polish and the Jewish were treated when they came here in the 1900s?

Answer 1

They were all boxed in in their nationalities part of the city (little italy for example). Tenement housing was notorious because it was the only places they could afford. It was extremely hard for them to get by because of the racism in America.
TL;DR Racist america made it a very hard life for immigrants.
