One of the problems, When we compare the resiliency of past generations to today's generation we are comparing apples and oranges, the resiliency of today is based on modern technology and conveniences none of which will exist in short order after a total grid down. As Paul stated earlier, no tap water no food being transported to stores, no life saving meds, hospitals will be overwhelmed, how many will stick around to bury the dead? We have 11 cities with over a million people in them, resources will run out quickly causing the masses to venture further and further out not counting 150 cities with 300,000 or more people, we have 365 million people in this country, I will say famine will come in short order. No, we can't really compare to local events as I have above, I was only illustrating the breakdown. Most of these cities will bank on hope that the government will come in and save them, in a total grid down the people will not be the first priority of the government, the first priority is putting critical infrastructure back on line such as communication, law enforcement, airports, hospitals etc... The government doesn't have the resources to take care of the people without outside resources. Hunger breeds violence and that is a known fact many times over!
I don't put much faith on humanity thus one of the reasons why I prep, I'm under no illusion people will behave in a civil order 30 days out without food and water readily available. As I stated in an earlier post, the compassionate one's will be an early target of the unprepared.
