It is a difficult decision to determine whether one should leave their blight-ridden community behind and migrate to the suburbs. I think as far as safety is concerned, it would be in your best interest to move to an environment that would lessen the chances that you and or your children would become a statistic.
If there is a way out, then take advantage of it, but never forget where you came from. It is very important that we remember our roots and those that have been left behind. We should continue to give back to our communities and strive to make a difference, even if we are no longer physically residing in the neighborhoods we grew up in.
You can still make investments, volunteer, and give your time toward making advances. Hopefully all of your hard work and dedication will pay off and there will come a time when the middle and upper class minority will no longer join in abandoning our communities due to urban crime and poor educational standards.
You stated that you are at a point in your life in which you had thoughts of being a separatist, well, there are plenty of thriving black middle class communitites which you can consider settling.
