One of the many problems we have in our political discourse is the ease with which the media are distracted. So, along with straw men, false dichotomies, etc., we get crisis after crisis.
In the case of immigration we are being distracted by the "amnesty" charge. This is really beside the point. Immigration, like free enterprise, is good for the U.S. if allowed to find its natural course. The problem we have is that our generous welfare, food stamps, "Dream Act" tuition rates, "motor voter" laws, and so on ad in finitum, are attracting unproductive people. Just a mere few generations ago immigrants who came here, the "...tired...poor," were brave, intelligent, resourceful people who fled tyranny and poverty for economic opportunity.
