Sometimes its hard to read these posts. I live in the third world, and let me assure you that any time there is instability, people do NOT run to help each other here. It takes very little to break civilization when you are already on edge. And people DO immediately default into rioting, looting and murder here.
Also let me say that people are already suffering in many parts of the world, right now. I do home care visits, and was out the day before yesterday to see a woman with spinal TB who lives in a 10x10 mud room in a squatters slum behind a cemetery. She shares that house with about 8 kids and grandkids. The only food she had were a few packages of enriched porridge flour given out by the government at the TB clinic, but she had no way to cook it. She used to earn money washing laundry for others, but now her spine has collapsed and she is barely mobile. She has no money to buy food or charcoal or firewood, or water. She was burning her plastic jerricans to cook, but eventually ran out of plastic too. Pictures from Friday, not 1933.
