"Among experts, a furor continues to swirl over whether gentrification and displacement are conjoined. What qualifies as displacement, anyway? Forcible eviction by a rapacious landlord, obviously, but what about a rent that creeps up while a household’s income doesn’t? How about the intangible, dispiriting feeling of being out of place, or a young person’s knowledge that leaving the family home means living in another borough? Or the dislocation that comes when an industry flees, taking its jobs along? These pressures can affect investment bankers and nurses, as well as busboys and the unemployed, and it’s not always easy to distinguish coerced departure from a fresh opportunity, or gentrifiers from the displaced."
