More than 17 billion dollars a year is spent on paying for the anchor babies that get squirted out along with their follow up medical care. It costs 5K for an illegal to drop one and that is if there is no complications. Build the wall, Joe Asswipe....
Your numbers are even more questionable than your conspiracy theories, Dale Crazy.
the 17 Billion figure was just for MATERIALS. Then you have labor, land acquisition (You think some rancher is just going to let you tear up his land without compensation?) transportation and the costs of patroling it when it is built.
