As an Italian who studies awhile in Arizona I easily recognize the pattern of a crucial border: two worlds too close and at the same time too distant. While the islands of southern Italy attract hundreds of desperate Africans trying to gain access to a restful European life, the south-west of the United States appears less demarcated from Mexico and Central America in terms of ethnic composition, language, religion, culture, history. Here nations and populations seem to have always overlapped and blended. The substance, thought, doesn’t change. It is not forcing reality into ideological frames: it is to recognize the facts as they evidently are. The observation is as binding as physics law describing the movements of fluids from a more compressed to a thinner space. We find imposing immigrations together with imposing inequalities.
