I disagree. Every country's administrators create priorities and rarely are the traditionally unrepresented poverty-stricken and homeless high on their lists. Without the will, commitment, and overt support of the populace, little if anything changes. Homelessness has been around for thousands of years, if not forever, and in the 21st Century some smaller jurisdictions have made inroads reaching close to a 100% effective solutions. The strategic options and imperatives are there, it's just that many, if not most, people have become resigned to accept this blight like few others.
