You're downplaying a catastrophic loss of family. All of these people you're rattling off are connected to you and are part of your social graph, which is something humans thrive on. You disconnect people from a community (death loss of job) and you're likely to see homeless. It's one of the reasons people give up and succumb to living on the streets outside of mental illness (which is another major factor that goes into this). A clear means of treating this problem is to put people BACK into a community that has expectations and guidelines.
