Immigration is crawling its way back onto the national agenda. Earlier this year, Congress enacted a law intended to prevent illegal aliens from getting state drivers' licenses; the volunteer "minutemen" who recently patrolled the porous Arizona border with Mexico attracted huge attention, and members of Congress from both parties are now crafting proposals to deal with illegal immigration. Being brutally candid means recognizing that the huge and largely uncontrolled inflow of unskilled Latino workers into the United States is increasingly sabotaging the assimilation process. Mexicans are now the single largest group of U.S. immigrants, 30 percent of the total in 2000. Indeed, the present Mexican immigration "is historically unprecedented, being both numerically and proportionately larger than any other immigrant influx in the past century". In 1920, for example, the two largest immigrant groups—Germans and Italians—totaled only 24 percent of the immigrant population. Among men, about one in 20 U.S. workers is now a Mexican immigrant; in 1970, that was less than one in 100. Will immigration continue to foster national pride and strength or will it cause more and more weakness and anger?
