I believe that ethnic enclaves were positive.
Because they provided immigrants with a sense of community, cultural preservation, and economic opportunities during a challenging transition period in their lives.
Reason 1: Ethnic enclaves offered immigrants a familiar environment where they could maintain their cultural practices, languages, and traditions. For instance, areas like Little Italy and Chinatown allowed immigrants to celebrate their heritage and create social networks that alleviated the stresses of adapting to a new country.
Reason 2: These enclaves often served as economic hubs where immigrants could find jobs, start businesses, and support one another financially. An example is the garment district in New York City, where many Jewish immigrants found work in clothing factories, allowing them to establish economic independence while also creating a thriving community.
