Dave: I think we need to focus on the pre-existing conditions (the causes) of homelessness...they are many: temporary unemployment; escape from abuse (most often women, frequently with children,  and teenagers), mental health issues, chronic alcoholism, drug addiction, physical or mental disabilities, PTSD (sadly very common among homeless Vets); and, frequently, a combination of these conditions... each homeless person has his/her own "story".  Additionally, and of concern, is the population of "travelers"..persons who choose the vagabond lifestyle.  

I agree we, as a community, are badly failing these individuals.  I would suggest providing "temporary and transitional" housing is an important FIRST step in addressing these many issues and each person will need an "individualized" plan to help him/her move forward with life.  I also agree.. positive actions to help our fellow Americans in need beat spending billions on foreign military adventurism.  Regards, Gary Crum
