It's an incredibly complicated problem, but if there is one message I can share it is this: homeless people are, first and foremost, people. They span the full range of human experience (the main subject of my movie had a masters degree in psychology) and there is no one-size-fits-all solution. Homelessness is not one problem, it is a symptom of at least half a dozen different problems, all of which need different solutions. (And, BTW, some homeless people voluntarily choose the lifestyle. It's definitely a minority, but it's not zero.)
