I already said my piece on that. If I thought there was a place that offered me and my family a better life I would go. If it wasn't legal and the risk to reward ratio was right I would certainly try. If I could live better as an undocumented immigrant in one place than my home I would take illegal immigrant in a second. Survival is the most important thing, and it may sound harsh, but those people are doing what they need to to survive.
I think a person who is the byproduct of certain policy would more properly be termed refugees, they certainly are economically, and some are certainly fleeing from violence. But we call them illegal immigrants and the law is being broken, I think we should change the laws. To what, I don't know, I'm not an expert on border policy, or international relations.
