Things are getting worse (economy, weather, infrastructure) for everyone in SA be they black, white, or anything else. Part of what you are seeing is how people act out when they feel they have nothing left to lose. I do not know what is involved in leaving but I hope you are working your way through that process so that you can exit when you decide it is time. I understand people want to take their assets with them. I would too, but at a minimum be ready to exit on a tourist visa (or get your son out on a student visa) if things get to the point that we all fear may come to pass. At that point better to leave it behind and start over someplace else than to die trying to hold onto what you have.
