Stay, buy up the property and help the ailing.
I don't blame a person for moving to the burbs. There's better schools, roads, facilities etc. However you become "The Blac Neighbor". White folk gonna put their shit up for sale soon as you move in. Your kids gonna deal with being the Niggers at school. Constantly dealing with ppl who are jealous that you are on their level, yet you're Blac.
We have a stigma of chasing the White man's leftovers versus creating our own oasis. We get money, move out to the burbs, the White man moves father away. Then the White man buys up what was once the hood for pennies, and turns it into a desirable, expensive place, and we get mad and think, Damn why didn't I do that.
Stay with your ppl, buy the bloc, invest, employ and teach your ppl.
