I think the reality that needs to be confronted is that many, many neighborhoods were harmed significantly by a large range of occurrences over a good chunk of history. Redlining, first and foremost, if we're discussing neighborhoods. White flight from urban school districts is a closely related issue.

These happened. Redlining was in no small part due to direct federal policy. These have had impact on our neighborhoods, impact that can't be downplayed, and communities adjusted to survive. Gentrification in a lot of ways looks like the undoing of these policies, which would be fine, but look closer and you see that the neighborhood ecosystems are being strained yet again. Whatever equilibriums were obtained (many via struggle and sweat equity by families with ties to the area/no other options) are now being threatened.

I think reparations to neighborhoods, communities, and people directly affected by redlining is necessary, and would serve to lessen the power differential between communities and neighborhoods. Doing so would ease the problems created by population transfer.
