Post-Crash Gotham

Gawker has created with weird map of NYC on the possible rollback of the gentrification of certain neighborhoods in a post-recession economy. They note that trend stories are already being written about yuppies shrinking their advance into the hinterlands.

But I'm somewhat confused by the color coding on the map.

Pink for traditional strongholds of the rich that will remain unscathed. Red for core neighborhoods that are probably too gentrified now to roll back significantly. Pink for marginal hoods, where a recession could send gentrifiers fleeing. And grey for wilderness neighborhoods, where yuppies would fear to tread after The Poors take them back for good.

Two pinks? The Upper East Side is "marginal'? Huh?
