I am willing to see if Trump can get the wall built—if Mexico will not pay for it—charge them tariffs. Trump has too much invested in this wall to not do it. It will happen even if he must build it himelf.
The wall is one of the attractive things Trump has talked about, but of course he’s falsely bragging about ‘no one else even mentioned it’.
Regardless of how we get the damn secured border the better. Who pays for it is of less concern. Its highly unlikely Mexico will be the payer primarily for some of the reasons I outlined previously.
The best way to have 12 million ‘self-expell’ is to cut their free welfare, free medical and fine to holy hell out of any employer who hires anyone without a green card or a citizen. THEN, Mexico or Latin America home will look more inviting.
