The part I don't understand is, if it is purely mental illness and or drug/alcohol related, why is there a huge national problem in the last decade or so and prior to that hardly any? Not saying that wasn't homelessness before but I would say around here it is at least tenfold over what it was 20 years ago.
Carl, not all homeless are mentally ill or on drugs and alcohol, but all of them I have dealt with are.
When I was an undergrad, I worked for a security company over Christmas break, that had me hunting down the homeless people who would sneak into Chem Ed Center in Cincinnati, the parking garage and the underground tunnels that connected it to the Central Trust Building. It was like a strange LARP D&D Game. The building was under construction and extremely porous. The homeless would sneak in to steal and to find a place to sleep and stay warm. It's an immense building, 32 stories tall, 553,659 square feet above ground, with an immense parking garage, with several levels more underground including tunnels that connect to many other buildings, the sewers and electrical line tunnels. I could not walk it all in an 8 hour shift. The elevator only went part way up at the time and the upper levels were still open, with no windows. There were no lights in most of the tunnels. I had to use a flashlight. Some of the tunnels were lined with limestone and were probably built in the 1800s. The homeless would build nests under stairs, in the tunnels and in weird little rooms off of the tunnels, out of any sort of soft, warm material they could find. Some of the rag piles were nearly 2 feet deep. Some of the homeless would stay buried in until I pulled them out. I would find between 3 and 20 homeless people a shift, sometimes the same ones a few times a night. As long as they were cooperative, I would let them keep their belongings, minus any tools or building supplies they had taken and just escort them out.
After I graduated, a friend and I started a security company. We had an account with some upscale, loft style apartments in Dayton, where we had huge problems with the homeless, stealing and harrasing the tenants.
