How do we live with others?

I know this is past due but I think it's interesting to think about. I feel that we compete with others. We do not wish to live harmoniously. Though we like to think we do, innately I think human beings want to be better than each other. We live to support ourselves and the people we love. We would steal from another if it meant we could feed our family. We would kill if it meant we would stay alive. I think it is folly to mask the human beings natural desire to compete. Yes, I think it's natural. We want to be the healthiest and the smartest and the wealthiest and the nicest and the most powerful. I don't think it's a bad thing so much as a form of natural selection, survival of the fittest. Plants compete for light, they outgrown each other. Animals compete for food and for companions. We are energy and that energy in itself competes as we read in "The Post-Modern Fable". Humans capacity for competition stems from that feeling of necessity to outgrow and outlive the competing life forms.
