The U.S. decided to end the one-way immigrant flights into Mexico, which were intended to send undocumented immigrants a long way from the U.S. border. One silver lining out of an otherwise badly damaged immigration system is that the government does stop things that are too expensive and/or don't work as planned.
“Everything comes down to dollars and cents,” said George Allen, assistant chief of the Border Patrol’s Tucson sector. “We’re running into a more budget-conscious society, especially with the government.”
This also happened with virtual fences. Bureaucracies fight to keep their programs because they justify budgets, so at the very least it's good to see programs ended when they don't make sense anymore.
