"We have data that says its harder to get in, its harder to sneak in. We have data that shows the cost of hiring a smuggler has gone up, we know that the enforcement practices have pushed a lot of people who were trying to sneak into more remote areas so it is more dangerous physically…. But then when you look at the U.S. economy, it might be hard to find a job. You put all that together and it’s not all that surprising that many, many fewer people are trying to come into the U.S."
