Great idea! But it won’t work, Mexico won’t pay.
We need to tax remittances sent back to Mexico by illegals living here and or raise the price of border crossing permits I-94s. Those are both methods of collecting where they have no choice but to pay. There are other things that can be done as well.
To clarify I meant asking them to pay $2,000 per illegal...not workable. The rest...some is sketchy, some is workable.
It is actually simple to get Mexico to pay for the wall...there are many things that they would have no choice but to pay...that is what is workable.
