TAKE AWAY ITS EXOTIC AND ITS MAGIC, THE MARVELLOUS despair of Cien Años de Soledad, the Latino troubadours like Atahualpa Yupanqui who sing of peasant rebellions, love of land and patrimony, and sudden death; take away as well the tourists, the scenery, the churches, the romantic rebels and the outrageous caudillos, and indeed the whole vast mad throng of images which foreigners hold about Latin America, and we come to the heart of the matter, one unique theme, one common denominator, or perhaps better, one refrain, or one implicit major premise about the hemisphere. It is that everything has been tried and nothing works. Or, nothing works as it should. Even that which starts well won't last. Enterprises fail unless foreign owned and operated.
