Besides the whole racist angle and exploiting tribal lands angle, the biggest reason why this wall was a complete failure from the outset because ICE themselves have described physical barriers across the Mexican border as "speed bumps."
ICE says that it can take as little as under 20 seconds to circumvent or thwart border wall attempts. So it's billions of dollars wasted for no real benefit. The quintessential example of misappropriated government funds. Unless we want to go full authoritarian like East Germany and have troops every 10 feet who assassinate women and children who try to cross lol
I am SO glad Biden immediately stopped this shit.
