Despite its name, Smugglers’ Gulch is one of the toughest places to sneak into America. The narrow valley near San Diego is divided by a steel wall and watched day and night by agents of the border patrol, who track word-be illegal immigrants with the help of helicopters and underground pressure sensors. Rafael, a cement worker, has already been canght jumping over the fence five times. Yet he still wanders on the Mexican side of the fence, waiting for nightfall and another chance to cross. How much longer will he keep trying "Until I get through," he says.
Last week the Senate tried, and failed, to deal with the problem of illegal immigration. After much debate it abandoned a bill that would have provided more money for border security but also allowed many illegal immigrants to obtain visas. Yet the collapse of the Senate bill does not mean illegal immigration will go away, either as a fact or as an urgent political issue. Indeed, one likely consequence will be an outbreak of ad hoc law-making in cities and states.
One such place is Arizona, where the governor, signed a bill this week imposing rigid penalties on employers who hire illegal immigrants. Those who are caught once will have their licenses suspended; a second offence will put them out of business. Even the governor admits the bill is too broadly drawn and will be hard to enforce. She signed it, she explained, because the federal government has shown itself to be incapable of dealing with illegal immigration.
One in ten workers in Arizona is illegal, according to the Pew Hispanic Centre. So the law, if rigorously enforced, could disrupt the state’s economy, which suggests it will not be. One landscape gardener in Scottsdale who worked illegally for three decades and now pays illegal workers ＄7 an hour thinks the measure is ridiculous. "Who else is going to pick lettuces and trim trees in this heat" he asks, pointing to the sun on a 47℃ day. He has no plans to change his ways, and says he will simply move if he is caught.
Laws such as Arizona’s will make life more unpleasant and unprecedented for illegal workers. But they will not curtail either illegal immigration or illegal working as much as supporters claim. In any case, the border has been so porous for so long that people now have plenty of reasons to steal across it other than work. Of five aspiring immigrants who spoke to the correspondent in Smugglers’ Gulch earlier this week, three were trying to join their families.
