The trouble began with a Wes Anderson-themed crochet mural hung on the side of a building in Bushwick, Brooklyn.

If that sounds like the fabrication of an absurdist art prankster, it was not. It was, by all accounts, a sincere and well-intentioned decoration by prolific yarn-bomber London Kaye for the Bushwick Flea, an outdoor market set up in a parking lot in the rapidly gentrifying New York neighborhood.

The mural, which depicted the young hero of Anderson’s film Moonrise Kingdom holding hands with the creepy twins from The Shining, was installed overlooking the Bushwick Flea on an adjacent building. Unaccountably, it appears that neither the artist nor the market’s impresario, Rob Abner, asked the building owner’s permission to put the thing up.

The owner’s nephew, Will Giron, soon posted a complaint about the crochet mural on Facebook, alleging that Abner had been rude to him when confronted about the mural (a claim that Abner later denied). Giron’s post began with these lines, which resonated for many New Yorkers: "Gentrification has gotten to the point where every time I see a group of young white millennials in the hood my heart starts racing and a sense of anxiety starts falling over me."

Not everybody in the new wave of urban development is ready to back down. An article this month in Philadelphia magazine, entitled “The Death of Gentrification Guilt,” discusses the controversy over a pop-up restaurant, Le Bok Fin, which opened atop a building that had once been a thriving public vocational school. (Philadelphia itself outraged many when its most recent cover image, accompanying a story about the city’s schools, failed to include any African American kids—although 52 percent of Philly’s public school students are black. The editor issued an apology.)

In the gentrification piece, Holly Otterbein discusses the way that many “New Philadelphians” reacted to a blog post critical of Le Bok Fin and what it represented: "[T]he post struck a nerve, and it, too, went viral. Only not because anti-gentrification zealots were taking to Facebook and Twitter. Instead, it was an incensed band of young, privileged urbanites, including many of my friends and neighbors, that broadcast far and wide the musings of this newly minted amateur blogger. The post sought to shame them, and when it comes to remaking the city in their own image, New Philadelphians will not be shamed."
