Most of the people are good decent people who will look after their families come what may. They want to have the skills and the knowledge to survive as best they can. When an area is evacquated there are those who remain behind to loot and scavenge. They know the police won't come. There are people who have never made anything of themselves who feel entitled. Sort of like early communism. "If we just take everything away from the greedy rich people and give it to us, the world will improve." It has never worked. Mostly because the so called greedy rich are also the creative producers. Most disasters are short lived. If we have a really long one, I believe that the lazy and foolish will be replaced.
