One small part from
a long article by SDLP councillor Martin Morgan caught my eye.
No one street in most parts of New York is the exclusive reserve of any one group and no single shop has only one colour or nationality of person working or shopping in it.
Okay, I don't live in New York these days, but I figure there are still ethnic neighborhoods in New York. And, I have to imagine that there are still all sorts of retail businesses that are pretty much the exclusive domain of one group/nationality.
