Not sure on the exact statistics, but (outside of the lottery and chain migration crap) the USA has been in the immigration "brain drain" business for a long time. That is to say, we take the best and brightest of all the other countries that want to (and actually CAN) come here. Shouldn't the liberals, and indeed the UN and rest of the world, demand this be put to an immediate halt? Doesn't this give the best and most power and most advanced country in the world one of the greatest and most powerful advantages/resources that a country can have? Shouldn't each country forbid it's best from leaving and instead make them use their great (relatively speaking) minds and abilities to the benefit of their own homelands, often 3rd world cesspools that need all the help they can get? I think this would be a good idea. And if we aren't taking their best, well, we sure as hell don't need the rest. Seems immigration to America should be completely stopped and to some degree, if they have not become full LEGAL citizens, reversed. You know, for the good of the whole world, all its people and nations. Stop being so unfair USA!! Stop your evil practice of allowing immigration!
