"The problem of the illegals," as Governor de la Madrid expounds it, is a problem

of insufficient industry in Mexico, insufficient agricultural tools, and too high a birth rate. In a discussion filled with helpful detail, he calls for a comprehensive agreement between Mexico and the United States: "Then we can keep our people in Mexico.... Then the United States can say, 'Fine. If I help you in commerce and in trade, I in turn need energy.' Then we could talk about energy. We could talk about Mexico needing, say, reforms or changes in certain laws like, for instance, Section 602 of your Tax Reform Act of 1976 that limits the amount that can be spent by U.S. persons that go to Mexico on conventions ... I think we should live as neighbors.... And as neighbors do, if you need a cup of salt, go around the back fence and ask for a cup of salt, and in turn maybe next week you get a cup of sugar back."
