In your opinion, what are the causes of homelessness and how can it be eliminated?
Context: I was attending the APHA conference in Philadelphia (USA) in the city's biggest Convention Center but right in front of the Convention Center, in the covered street, dozens of homeless people were taking shelter, shivering in the cold weather. "Why this much inequality, or inequity?" I asked myself. All homeless were humans like the conference attendees, staying in the comfortable hotel rooms, enjoying the discourse on eliminating health disparities right across the glass wall. Why these two drastically different faces of humanity? Who is responsible? How can it be addressed? I kept asking myself.
