I guess I'm having a hard time envisioning this problem in St. Louis. I live in what's probably considered a "gentrifying" area, but since most properties around me are owner-occupied, no one's being displaced, that I can see. There's lots of rehabbing, but it's primarily people rehabbing their own homes.

Also, there's a ton of affordable housing within two miles of my home, judging by the real estate sales pages for this zip code and an adjacent one. The sales prices are quite varied, which I think is desirable.

Also, the Compton Gate condo development didn't directly displace anyone; it was sited on a vacant lot, so I have a hard time lauding anyone for its destruction.

FTR, I'm neither a hipster nor an empty nester, and those in my neighborhood aren't either.
