Anyone who stays in the cities is going to regret it bitterly, especially if they own their home there. If you don’t get out in time, you may never get out since property values head down to zero as crime rates, taxes, rise and services decline.
I worked for Burroughs Corporation in the 60's and was in Detroit during the MLK riots with the burning, looting and killing.
My family was back in Pittsburgh {my home} and when I returned my wife informed me that we were moving out of the city and we moved into Westmoreland County and it has turned out to be the best move that we could have made.
The place that we used to live is now crawling with hoes, pimps, druggies and more low life scum than you could shoot with a Gatling gun.
If you still own a home there, burn it down and collect the fire insurance or walk just walk away. It is a disaster.
What Detroit is doing today is a preview for what is going to happen in many, many major USA cities.
