Yes, that story came from Fox, but read its facts before you toss it out. And then get practical for what do we do? As soon as I get practical, I make someone mad.
Here is how I see it practically speaking. Three countries in Central America are facing drastic poverty and violence issues-- some of their violence is from the drug trade, for which the US bears some responsibility as a major user of illegal drugs. These countries seem to be going under in terms of government strength, and their people are frightened. They think the US has better answers (Some of them should visit Chicago to see how that works for them) and so they want to come here as you can imagine our immigrant ancestors did-- as everybody came here from somewhere else, including those who call themselves Native Americans. Evolution began in Africa, and outward from there spread mankind. That's a fact whether someone wishes to literally believe in a creation Bible story or not.
Today we are being asked to deal with an immigration crisis, while having a law in place that mandates cutting government programs through what they call Sequestration (with currently the exception of those mandated by law like SS, Medicare, Medicaid but which they get around by how they pay the doctors in the latter two) by a certain percentage each year to pay down the debt brought on by tax cuts and wars that were put on the tab.
An additional problem today is based on our own mythology, a lot of it based on how something is versus how we want it always to be. So the left, using the Statue of Liberty for evidence of our duty, says:
With silent lips. "Give me your tired, your poor,
Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore.
Send these, the homeless, tempest-tossed to me,
I lift my lamp beside the golden door!"
