For many generations Mexicans have illegally crossed the border into the United States. Reasons for the high rate of migration from Mexico include the close proximity of Mexico to the U.S. and the noticeable difference in the quality of life between the two countries. Many individuals come from poverty-stricken towns in Mexico and Central America, they desire to come to the United States to work the menial labor jobs that Americans will not and in some situations, to escape persecution and emanate death.
The issues that prompt a family to send a young child away from their home country on a dangerous trek to the U.S. have only gotten worse, namely gang and drug-related violence in their home countries.
For potential migrants who are calculating the pros and cons of trying to cross the border, stiffer U.S. security measures are making the trip much more expensive, in particular the exploding cost of hiring a guide. The journey has also become more arduous and dangerous, in part because the DHS has plugged traditional crossing points and driven migrants deeper into the desert.
