With apologies to Leo Tolstoy: All cities gentrify. But each city gentrifies in its own way. I returned last night from a five day trip visiting my daughter in New York City. She is spending the summer in Bushwick, a predominantly Latino neighborhood in Brooklyn (most residents hail from the Dominican Republic and Puerto Rico) that is now home to an increasing number of chic wine bars, single origin coffee shops and 20-somethings like my daughter. The intruders are provoking familiar debates about how to preserve local communities in the face of powerful market and demographic forces.
