To that point, we don't need a wall. What we need to do is enforce the federal law that makes it a crime for employers to hire illegals, and for communities to declare themselves sanctuary cities. That law -- Section 1324 of Title 8 of the United State's Code -- makes it illegal to smuggle, transport, harbor, encourage or induce, or aid or abet an illegal alien or aliens. The fines can be stiff:
First offenders can be fined $250-$2,000 per illegal employee. - See more at: http://www.legalmatch.com/law-library/article/penalties-for-employers-hiring-illegal-immigrants.html#sthash.ULDOE7St.dpuf
- First time offenders: $250 to $2,000 per illegal employee
- Second time Offenders: $2,000 to $5,000 per illegal employee
- More than the above: the fines can range from $3000 to $10000 per illegal employee and can include jail time.
Simply, the cutting off of the ability to find work and sanctuary could both slow and reverse our illegal immigration problem.
