Savings created by reducing illegal immigration through an effective border wall could save taxpayers more than enough money to pay for the estimated $12 to $15 billion cost of building the wall, according to a new study by the Center for Immigration Studies.
Because most illegals have low levels of education and earnings, they create far more costs to government than they pay in taxes: the lifetime fiscal impact (taxes paid minus services used) is a fiscal drain of $74,722 for each illegal border-crosser. The study concludes that the wall would pay for itself if it stopped a mere 9 to 12 percent of attempted crossings.
