It seems to me that every city has a invisible people. They are also known as the
homeless or the destitute. Some people can see them
and yet fewer are able to interact with them. To
me it seems that most people cannot see them. To
my
shame I am often blinded and rendered incapable of seeing them too.
Some countries have entire populatinos of invsible people.
Chile under General Augusto Pinoche had soldiers
who were specialy trained at making people invisible.
The Chinese regeme can make you invisible if you think the wrong thing or say say something they don't like, or help
someone say something they don't like.
The Russian politburo used to make lot's of people invisible until capitilisim made them invisible !
