One of the sillier arguments against securing the border is cost. Vastly inflated estimates are presented. But they leave out what failing to secure the border is costing us. As Dr. Steven Camarota at the Center for Immigration Studies points out, even if the wall only stops a fraction of illegal immigration, it will pay for itself.
A new report by the Center for Immigration Studies estimates that if a wall at America’s southern border stopped between 160,000 and 200,000 illegal crossers — 9 to 12 percent of those expected to successfully cross in the next decade — the fiscal saving would equal the estimated $12 to $15 billion cost of the wall. The analysis takes the likely education level of illegal border crossers and applies fiscal impact estimates, developed by the National Academies of Sciences, Engineering and Medicine, for immigrants by educational attainment. Based on the Academies estimates, each illegal border crosser creates a net fiscal burden (taxes minus expenditures) of approximately $74,722 during their lifetime, excluding costs for their U.S.-born children.
Of course the left denies that there's any cost at all to illegal migration, just benefits, but the reality is very different.
