We've all lost a job before, we get back up and find another one. What I notice is a lack of confidence in themselves. You sense a lot of weaknesses. Have never been confronted with a strong stand erect look you in the eye homeless person. They look down, or away from you.I can only tell you what I know about my city, but there are a lot of reasons people go homeless. Whether it be losing your job, substance abuse, major medical event, etc. The average homeless person is homeless for about 6 months. Then, often with help, they usually get back on their feet.
There are, of course, some percentage that is chronically homeless. Usually these people are severely mentally ill. And the US does not allocate adequate resources to helping them.
I get some suffer some mental illness which makes me wonde why are they allowed on the streets at all.
