Actually, dear friend @karenb54, I believe that government is probably the primary cause of homelessness. Government robs us all at the point of a gun, and makes up oppressive "rules" (for example, restrictive laws and regulations) that prevent people from building and occupying their own shelters within their own means.

If we were "allowed" to build our own shelters using available materials and without tens of thousands of dollars in fees, there would be far fewer homeless walking the streets.
