So now there are 483,000 new jobs availiable for low wage/low skill workers. How convenient, and their families can collect welfare, free medical care, free tuition, afirmative action, etc.. And of course the evil corporations benefit, once they pay their taxes.
In reality, the only way to really prevent invaders is to physically protect our borders. All the rest is just pi**in in the wind.
Maybe you can get your congressman to introduce a bill to build the fence and put a 100,000 marines on thr border. Land mines and all that.
