I don't think there is a lack of that. I do think the fuel in the cities will run out fast and their ability to exit the city very far will limit the damage they can do, at least in the short term. In addition many country dwellers have weapons and know how to use them. They also know the lay of the land and how to hunt and prep it.
Both you
@DB and
@DiogenesLamp are giving way to much credit to country folks and thinking city people will die and roll over quickly just because they are liberal city folk and country folk are like Hank Williams JR songCountry boy can survive.
I live in a semi rural area.. maybe 1-2% of the local populations grows their own food and I am being generous. How many people still hunt?
The entire country and most rural areas are on at least county water, not well water and their water would stop as soon as the grid goes down and the pumps stop.
Country people would wither up and die at rates as much as the city people when their meds stop flowing.
I mentioned before about IQ and fitness. My area has suffered a brain drain as all the educated people leave. The smarter people or at least people with the knowledge to make things happen -logistics, medical, etc have moved to larger urban areas.
Everyone in my semi rural area or at least a majority are obese and out of shape..not so much for larger population centers which tend to be fit and fitness centers and gyms on every corner.
I just don;t think it would happen as you both imagine it.
Most cars get 300-400 miles on a tankfull..easily driving distance to most country towns
