economists put the wall's price at least $25 billionThe Southern BorderThe border between Mexico and the United States is 1,989 miles long. So what's the price tag on his "impenetrable, physical, tall, powerful, beautiful, southern border wall?" The United States spent $7 billion protecting 652.6 miles of the southern border and that was only for fencing. The United States Border Patrol has roughly 21,000 agents. There are less than 400 agents guarding the northern border which is over two and a half times the size of the southern border.
