“If remittances stop, those families will come here rather than stay in Mexico.”
Not with a wall, deportations, and punishing employers that hire them.
Your ‘arguments’ are silly liberal crap. Nonsensical
Enforcing employer sanctions will work, at least as to a lot of illegals. (Many work off the books and will continue to, but the ones that are on a payroll will self-deport if e-check and employer sanctions are rigorously enforced.) But you didn't talk about that-- you were talking about taxing remittances, which won't work.
