Illegal immigration is already way down. It could be cut to a trickle with the wall added. Multiply the savings to taxpayers of each of those people who does not come here illegally and the wall will easily pay for itself inside of a decade.
Illegal immigration was already way down and continuing to drop. It was a trend in the making before trump took office that has simply continued. Please get out of the fantasy world where trump came along and the previously spiraling out of control illegal immigration problem immediately reversed and dramatically dropped. That simply isn't true.
As for the wall, it would be a gigantic useless waste of money. The wall simply won't do a damn thing. Why? Because not only will those intent on coming across our southern border find a way around, over or under the wall, but they only represent a small portion of the folks in this country illegally. Most of the undocumented come here legally and simply overstay their visas. How's your precious wall gonna stop that? And one more thing... we were promised that Mexico would pay for the wall. PERIOD. He said it time and time again and it was a cornerstone of his campaign. So anything short of Mexico actually paying for the wall is completely unacceptable. Face it, you and all the other Trumpanzees (I know I know... you aren't a trump supporter and didn't vote for trump ) have been conned.
