You're acting like this is New York or SF, we don't have 400k extra people handing this way soon and Philadelphia has historically been a City of homeowners. It's true that desirable locations are limited but even those are still incredibly underdeveloped now.

I'm Fishtown adjacent and my neighbors that bought their houses for $5-15k in the 80s and 90s are very happy about the changes to the neighborhood. Many bought empty lots near their houses for next to nothing and sold them for incredible profits. "Gentrification" is such a vastly diverse experience based on hyper local circumstances that the term is near worthless and just used as a boogeyman for change.
