Two of my coworkers are homeless and in just that situation. I'm somewhat astounded that you can't see any reasons why people don't want to just pick up their lives and cut all ties to go somewhere else.
I would like a trial job and a trial house for 6-12 months. Ill find something myself. It should probably involve a schedule with social interactions and someone to monitor the progress. Other people who just relocated are probably interesting to talk with.
