I know this letter comes from a deep place of consideration. However, the main cause of homelessness is not having friends and family to bail you out when you hit a financial crisis: unemployment, rent increase, big medical or family expense. It's no more complicated than that. Friends of mine who live with their parents because they can't afford housing in the current economic climate are not considered people who are superficially tolerated and given false compassion. On the contrary, they receive oodles of public sympathy about the job market and price of housing. This is because they are socially connected enough to have a place to go when they find they can't support themselves. That is the only difference between them and many homeless people.
