I'm thinking you have no idea how human beings as a whole act and conduct themselves during desperate times of survival. If you somehow think all of your neighbors are going to work collectively with you during such times I think if we ever see such times in our life you will be terribly disappointed. My dad grew up during the depression. He told me stories that described to me just how far people will go. One thing about it, music changes, fashion changes, technology advances and our surroundings change. One thing that never changes is how the human mind functions. A large part of our society revolves around power and greed. And maybe the word neighbor is different for some people. It may not be people on your block. It may be people from a different neighborhood or town. But when people become desperate they will resort to desperate things. Make no mistake about that or the mistake you make could cost you more than it seems you currently think it will.
