Will The Border Wall Pay For Itself. The wall will also be paid for, indirectly, by the great new trade deal we have made with mexico. Like everything else they tell us, this is a lie.

The border wall he is proposing would pay for itself, and then some, in a remarkably short amount of time. As for the rest, it might be only moderately useful. It pays for the wall, it's good tax policy and there is nothing mexico can do about it the way i see it is, the wall should pay for itself if it is effective, camarota said.
Camarota crunched the numbers and found that if the border wall cut an expected 1.7 million illegal crossings by 200,000 — about 12 percent — over a decade, it would pay.
This question was originally answered on quora by josh velson. Congress must fund the border wall & prohibit grants to sanctuary jurisdictions that threaten the security of our country & the people of our country. If a border wall prevented 160,000 to 200,000 illegal crossings (excluding descendants) in the next 10 years it would be enough to pay for the estimated $12 since the border wall would by definition only impact the flow of those who cross the border illegally and not those who overstay a temporary visa. The border wall would very quickly pay for itself, trump said.
