I know refugees well, my wife worked to resettle them for almost 7 years and we had many friends who were refugees from Bhutan/Nepal and various countries in Africa. She herself worked with refugees from Iraq.
The vast majority of these people are not fighters. They could care less about politics. All they want to do is drive a nice car, live in a big house, have lots of kids, and live our exported American dream in peace.
Unfortunately, as you can imagine, the reality sets in when they come to America. The most common trend we've seen is that most refugees believe that all jobs in America pay really well, and nobody does labor jobs. What they find is that the only jobs open to refugees are labor jobs that pay poorly. Biggest hurdle to employment? English skills.
The Arabs are probably the worst when it comes employment after resettlement. Why? They come from nations that have been developed off and on for the last couple of decades. My wife has resettled teachers, doctors, engineers, journalists, all with credentials that are worthless once they resettle. They come here wanting to drive a Lexus and live in a huge house, only to live in what we'd call a slum.
What sucks is that the realities of life based on higher populations of people with lower than average skills or worthless credentials isn't told in stories back home. Refugees rarely call home and say "it sucks here, finding a job is hard, stay home." They say "American's don't like us, they don't give us work, we are starving, but its better than our war torn home. Come help us pay rent."
Despite lack of work, poor living conditions, language difficulty and other issues, many refugees stay in the USA and Europe for one main reason: peace. Even the worst case scenario in the developed world is still better than living like a king and trying to raise a family in a war zone. We offer free schools, rule of law, freedom of religion, and an informal economy that allows many refugees communities to thrive, even if they aren't formally employed. They know to pay taxes and aspire to own homes. Most of their kids value education and become quite successful contributors to our economy.
I'm not sure which is better: a nation like North Korea where brainwashed starving people live out their lives locked inside their borders, or countries that go through boom-and-bust periods like those of the middle east. Is it better to let lock a humanitarian crisis within the borders of a nation at risk of genocide or mass murder, or let the wars and its causalities spill out in neighboring countries?
We obviously can't seem to prevent the war from starting, can we do anything about the aftermath?
