I wish I could remember where I first read it, but from what I understand the average long term homeless person is a middle aged disabled man with either a mental illness or some form of substance dependency. Many are also veterans. It seems silly to tell that person to bootstrap. So for 11k a year for a roof and social worker vs. 16.65k for E.R. visits, jail, etc it seems like a no brainer. that's 5.65k in savings each per year.
