I truly appreciate this article, Sister, and agree that NAFTA has aggravated the economic situation of Central America.  Yet, the fact is that American policy has long played a substantial role in creating the misery that now occurs in Central America and Mexico.
Also, no one is "jumping" any line.  People who are living in misery and danger, far greater than many of us can imagine, are bring driven by sheer desperation to a better life.  People like that used to come here for many years; most were not welcomed, but tolerated.  But through most of that time, with some exceptions, it was possible for them to settle here and remain.  For some time now, we have embarked upon a heartless path of sending back many of those people to the misery that they flee.  This policy is heartless toward the newcomers and in counterproductive for the US.
