I got the fuck outta there but honestly it depends on what your relationship to that area is. We moved all the time so I don't have just one hood I got love for and know everybody in. I'm cool with some niggas, others not so much. In every area I know.
But I also know people born and raised on the same block, same house, and still there today. 3 and 4 generations of their family is still there. To me, those are the people the community truly belongs to. Even tho these are the kind of people that are less likely to ever have the resources, I understand why they would stay and build.
I would definitely contribute if and when I can but I wouldn't move back, try to raise children there. Feels bad sometimes but I got long time "friends" that have never met/seen my wife and kids in person and most likely wont. When I do come thru I try to come in different cars and I ain't staying long at all.
