What metaphors are used in Same Kind of Different as Me: A Modern-Day Slave, an International Art Dealer, and the Unlikely Woman Who Bound Them Tog' by Ron Hall?

The hobo jungle is a term for the area where homeless men gather underneath an overpass. The area is squalid, filthy, and dangerous. Homeless men smoke and drink in the jungle under the cover of night where no police or well-intentioned mission volunteers can stop them. It is a metaphor for sickness and poverty.
