Was the enclaves positive for immigrants

Many immigrants migrate from the coastal plains and settle in America in order to live a hassle free life hence the emergence of Ethnic enclaves encouraged the immigrants to be open to various culture and languages.

Ethnic enclaves are most common in North America. These enclaves are mostly residential areas which are formed particularly for a certain ethnic groups. They are self-reliant and the success of the group depends on the resources available in the enclaves or ghettoes. These Enclaves are in the form of tourist spots. Economic activities bustle in such areas.  

Chinatown in North America is an ethnic enclave which was open to Christianity.
