I think it is mainly a question of numbers. More Hispanics can come here than Irish, or Russian, or [Pick your favorite immigrant here]. This is mainly because they can pretty much walk right on over, whereas most people cannot swim far enough to get here from other countries. So, do Hispanics (Mexicans whatever) hurt our economy more than any other immigrant? I am sure that the influx of people that exceeds projected population growth has a minute impact on economists (but who likes economists anyway?). If this really bothers you that so many are comming over, just keep in mind that if enough of them come over, thier army will be small enough we can crush them and then set up the State of Mexico as the 51st State of the Union. Next is Guatamala, Hondurus, Panama (we practically own them anyway), Belize, and the rest of the Central Americas. Then we will have to turn our attention to the illegal drugs comming out of Columbia and Venuzuela. We will bomb the horse-pucky out of them until we have to swoop in to rescue thier government. This will cause them to subject themselves to the Union as well. Then, Canada will fear us and bow at President Arnold Schwartzennegars feet, and we will turn our attention to the rest of South America. We will then cash in for our extra armies due to us for controlling all of North America, and South America, and invade Africa. We will set up a barrier in Alaska to protect us from those pesky Asians, and also in Greenland (which will finally become a real country by joining the United Western Nation of America). Our plan will be to take all of Africa in one fell swoop, thus granting us an extra 3 armies......
