Alright, I have it...the tipping point for illegal immigration. First, this is based off the premise that illegal immigration is indeed an epidemic that needs to be addressed. So, if you can't concede the problem, then obviously no solution is needed. For those who are looking for a solution and don't like the financial repercussions of a Great Wall of Mexico, how bout this? If an American corporation knowingly hires an illegal or undocumented worker, the worker responsible for the hiring receives 6 months in prison.
