What do you propose? Cracking down on homeless people. Heavy fines and jail time? Is that somehow going to make them less homeless?

The only viable answer is programs like what this article is talking about. Providing consoling/rehab services and helping people turn their lives around one at a time. There is no blanket solution. These are individuals that are suffering and trapped in a cycle.

If you think violently oppressing the already downtrodden is a good solution please leave and go to another city. This is probably not the place for you.
