One word describes all this... SAD
I visited San Francisco in the middle '90's just after the earthquakes, late afternoon the homeless would start to set up their nightly accommodation not caring who they impacted, I can now only imagine how much worse it has become.
When people in power think that throwing money at a problem instead of getting to the root cause doesn't help, research has shown that many choose to live on the street forming a cultural group of their own kind in defiance of the accepted norms of a responsible society.
If they get enough to support their drug habits, not all are addicted at first but many once moving into these groups experiment and become addicted.
This behavior is happening all around the world and growing, their attitude is that they are victims and need to be supported, many do have family and friends but they have rejected them preferring the handouts they get from governments and from begging.
