What would have been an advantage to living in an ethnic enclave?

Most people would share your culture.

Explanation:

"New immigrants quickly settled in major cities like New York and San Francisco because these cities had neighborhoods already filled with people from their native lands. Living in neighborhoods like Little Italy or Chinatown had advantages and disadvantages. The advantages included being in a close community of people who spoke the same language."

One of the main advantages of living in an ethnic enclave is the protection of discrimination that provides the community living in the ethnic enclave.

Every ethnic enclave is a form of segregation. The unicity of the enclave and the particular identity of its community provide unique opportunities and social rights for being part of this community. If you are being discriminated for being part of a specific culture thus you can not get a job in a mainstream city company, your ethnic enclave community could provide you a job offer just for being part of it.
