“Is immigration causing cultural ghettos in cities?”
That was a question recently asked by a New York-based reporter.
She added, “And should we be worried?”
Not in my view. Cultural enclaves, in many ways, are natural. 
When immigrants first arrive in the country, whether they speak English fluently or not -- feel more at home in the company of fellow countrymen. 
This does not mean such areas should be viewed as an aberration, or as an unhealthy development. Rather, they should be seen as not as a blemish on our country, but as a positive indicator of an increasingly diverse populace.
