Panorama's Hilary Andersson comes face to face with the reality of poverty in America and finds that, for some, the last resort has become life in a tented encampment. Just off the side of a motorway on the fringes of the picturesque town of Ann Arbor, Michigan, a mismatched collection of 30 tents tucked in the woods has become home - home to those who are either unemployed, or whose wages are so low that they can no longer afford to pay rent. Conditions are unhygienic. There are no toilets and electricity is only available in the one communal tent where the campers huddle around a wood stove for warmth in the heart of winter. Ice weighs down the roofs of tents, and rain regularly drips onto the sleeping campers' faces. Tent cities have sprung up in and around at least 55 American cities - they represent the bleak reality of America's poverty crisis.
