I doubt an EMP, if the results are what has been printed, would do anything but put all of us back to not even Mad Max. (At least their vehicles still worked) After the Great Die off those remaining will be allowed to kill and eat each other until some other power decides its time to move in and begin taking the natural resources, should anyone else be still there.
We survive and live until the day we don’t. That holds true even in this chaotic “modern” society. Just take what comes as best you can.
