Once the power grid goes down, and computers can't tell anyone what to do anymore, the goody-two-shoes from the churches will release all the prisoners, and start caring for hospital and nursing home patients.
While the rednecks are raiding convenience stores , bars and liquor stores the prisoners will immediately raid all the hospitals, nursing homes, and pharmacies...... because they are the only ones that realize where all the truly beneficial stuff is. And they'll use THAT to aquire everything else it takes to bring society back to life.
Yep, the ones that have had nothing to do besides sit and think for several years are the ones who will be the new rulers. And in the end, things will be running way better than they are NOW. Guarantee it.
