Civilization is the process or condition of social organization characterized by subordination of competitive, selfish behavioral values and mores to cooperative ones in order to facilitate the ability of individuals to live peacefully and prosperously in close proximity with one another.
The process of civilization of homo sapiens sapiens has been underway for some five thousand years at least. That is when the first large communities began to form. It is still underway, most intensely in third world countries where people are increasingly leaving the rural areas where they lived in relatively small family groups and moving into large metropolitan areas in hopes of a better life. Not having learned to deal with strangers at every turn, they often find that the familial love and discipline that formerly governed their interactions is absent in the slums they make their homes in the big cities.
The existing social organization that we call civilization in the cities which are receiving these (often) un-cultured immigrants is often stressed by their arrival. It is stressed because of the pressures the new arrivals place on the job market, social services, utilities and law enforcement. More people, particularly in places like Central Asia, West Africa, S.E, Asia where there are economic booms in the big cities, find on arrival that they haven't the education or skills to "get a piece of the pie" and so they, in order to live, revert to thuggery, prostitution, selling drugs - or worse, form themselves into gangs that prey on the innocent. This sort of activity contributes to stereotyping, racism, and with the aim of protecting the "haves" already living in the big cities, the passing of laws and regulations that restrict access of the rural poor to things like education, health care, etc.
It, to some degree, is happening here in the US through illegal immigration, encouraged by employers anxious to maximize profits by exploiting them.
