Believe it or not, there are those who live outside of the system; they do not own a birth certificate, they do not have an identification card, they do not have a bank account of their own, they do not own a computer and they do not own a cell phone.
You may think that such people only exist in so-called primitive cultures or remote tribes in the desert or forested areas in other parts of the world. But, there are some people who are living outside of the system that reside in well-developed countries like the United States, Great Britain and Canada, to name a few. It is hard to comprehend that such a thing is really taking place in the 21st century.
But, why would people choose to live like that? I could only speculate the reasons why a person would choose to do such a thing. Maybe, they have made the conscientious decision to remain undetected and for some unknown reason, they prefer to be ghosts within our modern-day society.
