Why there are so many homeless people?

I just cruise around downtown Atlanta the other day to look for a building as my destination. I realized that there were so many homeless people in downtown Atlanta. They stand in line waiting for charity providing shelter, food, and medical aid. Some even stand around the street corner, and ask for changes. Some even gone mad and shouting at incoming cars. That really makes me afraid to get off my car, and less travel to downtown Atlanta due to this aspect of the city. Majority of them are black, and shouldn't they even attempt to get a job somewhere to make improvement on their lives? What do you think?
