Homelessness and compassion fatigue

I ride my bicycle past many homeless folks every morning. It's early morning and they have been awake for some time, congregating at several spots along the bike path. Some smoke; others telling stories, jokes and laugh. Some would be yelling, spitting at no one or nothing in particular. There are abandoned trash, dirty clothes, styro foam cups, take out containers near where they stand, sit, lie or strewn alongside the bike path near the creek. 

Loners prefer sleeping on the grass away from the crowd. They would be preparing their panhandling signs for the day. All smell bad. Students on foot, bicyclists, and runners mostly ignore the homeless since their compassion is overloaded. I wonder why these people do not get the jobs that the illegal aliens who do not speak English as well and with no legal status are doing.
