Homelessness is, by definition, a housing problem, but America’s Secretary of Housing and Urban Development, Dr Ben Carson says it’s not his problem, “not a Federal problem, but everybody’s problem.”  Which usually means, it’s nobody’s problem, except the millions of people in America who go homeless every night.  Alastair Gee runs The Guardians’ investigative project on homelessness, Outside in America.  He reports a lot of cities are solving their homelessness problem by handing out one-way bus tickets out of town.  Some solution!
