“What happened to the idea of taking a percentage of remittances that people send to Mexico?”
If you’d read the article you’d know.
“Mexico, Trump has committed, will somehow end up paying for the border wall, whether that comes in the form of taxing remittances to have illegal aliens from Mexico actually pay for the wall or tariffs on imported goods from Mexico.”
A tax on imported goods from Mexico won’t be paid by Mexico. It will be paid by Americans buying the goods.
That said I don’t care who pays for it.
Just build the damn thing.
Two problems with that. First, how do you identify illegal aliens from people here legally? And two, if you put a tariff on imported goods then Mexico doesn't pay for it, American consumers do.
