Do we still get the wall and who pays for? Are we going to just take that transfer money and tax it? That would just DRY IT UP. Mexico would wait us out. The money would find it's way to Mexico by other means than by wire transfer. Storefront operations would be set up to move the money. The Mexicans are clever people. They would find a way.
Just more Trump handwaving.
Are they inscrutable?
They get 25Billion in money transfers a year, it is most of their economy. They will cave pretty quickly. And I say invest it and use the profit to pay our other expenses.
