Here's the problem; the influx of those who come across any of our borders knowing full well they are here secretly and are not here legally have long been tolerated as a matter of inconvenient exigency but that was before the wholesale march northward that we have seen in the last 40 years, made worse with every amnesty program sold politically as a way to defuse a touchy, ticking timebomb of cultural disruption.
The current focus on national security demands that we address the concerns that have gotten worse with every passing year since 9/11 because the world is watching and there is a growing perception here that we are losing the very identity that made us an inviting target to begin with.
America, the U.S., can no longer afford to treat warrior scouts as ordinary tourists, motives are paramount and I.D. must be established at the expense of host and guest alike; this party has just begun so the message to all is, mind your manners, clean your plate and we'll count the silverware when the guests go home.
People forget that this is also exploitation. As soon as a worker gets "amnesty" the employer is just going to look for someone else that's illegal and easy to intimidate! Those who suffer most from black market labor are recent legal immigrants. Anyone at the bottom rung, or starting out, is going to suffer.
This "compassionate" business is crap. There's no compassion about it--the truly compassionate thing is to protect the law-abiding by punishing the law-breaker.
