Very simple Vince.. will not let anyone wire transfer or take money from US to Mexico with out a “Tax”
Two barrels of free oil per day per illegal.
Add to it:
Every illegal alien (yes, that is the legal definition) detained and awaiting extradition from the US requires a food and lodging expense in federal or state contracted facilities.
The expense is deducted to the over bloated foreign aid provided to Mexico on a yearly basis.
I figure that wall will be paid for to include a maintenance contract within a year.
