ent rate will increase 30 percent, as these children become young adults, in search of work. There were in 1990 an estimated four million illegal aliens in the United States, and about 55 percent of them were from Mexico. These people look to the United States. Human population has always moved, like waves, to fresh lands. But for the first time in human history, there are no fresh lands, no new continents. We will have to think and decide with great care what our policy should be toward immigration. At this point in history, American immigration policies are in a mess. Our borders are totally out of control. Our border patrol arrests 3000 illegal immigrants per day, or 1.2 million per year, and Two illegal immigrants get in for every one caught. And those caught just try again! More than 1 million people are entering the U.S. legally every year. *From 1983 through 1992, 8.7 million of these newcomers arrived -- the highest number in any 10-year period since 1910. A record 1.8 million were granted permanent residence in 1991. Because present law stresses family unification, these arrivals can bring over their spouses, sons and daughters: some 3.5 million are now in line to come in. Once here, they can bring in their direct relatives. As a result, there exists no visible limit to the number of legal entries. Until a few years ago, immigrants seeking asylum were rare. In 1975, a total of 200 applications were received in the U.S. Suddenly, asylum is the plea of choice in the U.S., and around the world, often as a cover for economic migration. U.S. applications were up to 103,000 last year, and the backlog tops 300,000 cases. Under the present asylum rules, practically anyone who declares that he or she is fleeing political oppression has a good chance to enter the U.S. Chinese are almost always admitted, for example, if they claim that China's birth-control policies have limited the number of children they can have.
