President Trump is not talking about building the Great Wall of China. He wants walls in strategic places to allow the Border Patrol to function efficiently. Wherever a wall has been built such as San Diego or El Paso it has reduced illegal immigration by 95% or better. Immigration costs Americans $116 billion a year. In addition, there are murders, assaults, theft, kidnapping, sexual assault and rapes, and other crimes. Here are the stats for Texas alone. https://www.dps.texas.gov/administration/crime_records/pages/txcriminalalienstatistics.htm
Trump is asking for a total of $26 billion to finish the wall. It costs $116 billion a year. If the walls reduce the $116 billion spent on illegals by 95%. The wall has paid for itself in the first year. Then President Trump could charge a border crossing fee or increase current fees for commercial trucks crossing the border from Mexico. Mexico charges Americans a vehicle fee to go into Mexico. Mexico pays for the wall.
