The cry of the invisible

The cry of the invisible: "In the 1960s, when I first went to Latin America, I travelled up the cone of the continent from Chile across the Altiplano to Peru, mostly in rickety buses and single-carriage trains. It was an experience my memory stored for life, especially the spectacle of the movement of people. They moved through the dust of a snow-capped wilderness, along roads that were ribbons of red mud, and they lived in shanties that defied gravity. 'We are invisible,' said one man; another used the term abandonados; an indigenous woman in Bolivia unforgettably described her poverty as a commodity for the rich."
