Where Green Trumps Black and White; In Harlem's Business Boom, Victors and Victims Come in All Races
First the rent on Desmond Parkin's optometry business on 125th Street in Harlem went ''through the roof.'' Then a Sterling Optical store moved in across the street. Dr. Parkin, 36, had thought he would retire in Harlem. Instead, unable to compete, he decamped for Brooklyn, abandoning his old space to a Starbucks coffee shop. In the fate of Dr. Parkin, who is black, would seem to be inscribed all of Harlem's worst fears about the remarkable economic development along 125th Street: that small black businesses will be crushed by an avalanche of outside (read white) capital trolling for profit, and by landlords looking to capitalize on it.
