Big Money: In a press conference with the President, Democratic leaders in the House and Senate, Nancy Pelosi and Chuck Schumer, declared that a $5 billion border wall is a waste of money. It’s nothing for the Democrats to approve $150 billion in spending and send it all to Iran, but when it comes to doing something for the safety and security for the people of the United States, it’s a “waste of money.”

And, according to a 2017 cost analysis by the Federation for American Immigration Reform (FAIR), illegal immigration costs U.S. taxpayers $155 billion annually. If the U.S. built a stronger border wall and enforced immigration laws, then the wall would pay for itself almost immediately and begin saving the country tens of billions of dollars each year.

…

The amount that illegal immigrants pay into the system at the federal level is a meager $15,447,897,700 and $3,520,960,000 at the state and local level. After doing the math, illegal immigration imposes a net fiscal burden of (115,894,597,664)USD.
