Many Americans feel that the United States government is not in control of the border and that the lack of control is a deliberate government policy. Nothing could be further from the truth. The government has greatly expanded the scale and scope of immigration enforcement on the southern border in recent decades.
The government built fencing on the southwest border and increased the mileage from zero in 1990 to 653 today (Figure 1). Some of that fencing is porous and much of it is made to deter vehicles, but it is located in some of the previously most heavily trafficked areas. The effect was that unlawful immigrants were forced to cross in new, more dangerous areas. President-elect Donald Trump said he wants a 1,000-mile wall at the border, which means he’s already most of the way there.
