Carlos Villarreal disputes some of the common arguments for clamping down on immigrants: "behind the scare tactics of Lou Dobbs and Bill Frist, the truth is that immigrants have strengthened our country and any negative effects of their presence are outweighed by the benefits. Furthermore, there are indeed policies that are burdening our country and many working people--the war in Iraq, tax cuts for the very rich, corporate greed--but loose restrictions on immigration are more a benefit than a burden."
