I try to have more compassion for the homeless because often the only thing that separates us are our circumstances in life, and those can change w/o warning: loss of a job, stock-market collapse, a serious illness, robbery or identity theft, etc. Not all are bums. Sure there are those who have addiction problems or mental illness, and some will never be able to hold a job. How easy would it be to get a job w/ no phone and no address, no way to clean up and dress presentably? Even the resilient ones will eventually get a warped sense of reality or lose their edge. They exist in survival mode and live in fear for their lives.
