Can anyone figure out the "dreaded G word"?

While the excitement or apprehension of bringing Whole Foods Market to Englewood has largely died down within the past month that doesn't mean we can't continue to discuss the "dreaded G word". That's what Atlantic Cities discussed in this quote with Amanda Burden director of NYC's planning department:

"What we haven’t figured out is the question of gentrification," Burden added. "I have never, since I had this job, come up with a satisfactory answer of how to make sure everyone benefits. It’s a question I would welcome more answers as to how to make this a more equitable city. Because that’s how we continue to attract people from all over the world, is people perceive the city as an equitable city, and a city with opportunity for all. It’s not just those poetic words. But I really wonder how we can do it."

This quote is partially in response to whether or not the free market should decide the issue of affordable housing. On gentrification however it's safe to say there aren't any easy answers are there?
