The history of society is real basic.
We began as a herd. (It is our natural disposition: vocally able to express our selves with detail, and very capable of learning empathy.) We moved together minding each other for all our good. After a certain time this changed, we became top of the food chain. The necessity to pay attention to our neighbor we thought was less important. Before in the herd paying attention to what others were doing kept us alive. After the herd began to spread out. People began to see that if their house was a little better than other people than perhaps they needed more space; if they got a little more food than perhaps they earned it. This focus that became less on the herd gradually had more people accidentally bumping into each other, some people getting a share that lacked adequateness… The focus for getting along, the safety of everybody, notice of became less. And from what I can tell from my knowledge of history, it has been that way ever since.
