Words are always shifting in their meanings, but what has happened to the word “gentrification” is something of a special case. Not too long ago, it was pretty much a value-neutral term for the process by which communities exchange one set of residents for another. Now it is a term of opprobrium, a word that conjures up the cruel displacement of defenseless poor people by a greedy and arrogant professional elite.

There is a whiff of hypocrisy in all this, or at least a strong element of disingenuousness. Ask mayors what they wish for in their city centers, and they will give you similar answers — safe streets, bustling sidewalks, busy stores and restaurants, and a healthy and growing residential population with plenty of money in its pocket. Mayors and city planners spend much of their time maneuvering to create these things, but with one inevitable disclaimer: They don’t want it to lead to gentrification. What they choose not to admit is that the change they are seeking and the change they claim to fear are exactly the same thing.

As “gentrification” has become an increasingly dirty word, the volume of disingenuous posturing on the subject has increased dramatically, and the supply of balanced reporting has declined. One writer who has managed to speak sensibly above the din is Kay S. Hymowitz, a contributing editor at City Journal and a senior fellow at the Manhattan Institute. “The New Brooklyn” is her admirably clearheaded assessment of the borough that sometimes seems the epicenter of American gentrification.
