This would so much more fun if it was an "us" issue. Our companies and individuals are hiring people who are not legal. If you manage hiring, you manage most of the issues discussed, but we want cheap everything, clothing, food, floral products, etc. We want the individuals who pick our crops, but not the ones who move next door.
Get pissed off about the violence regarding drug trafficking. We are the consumers. We are the country that has the ineffective laws regarding drug use. We are supplying the weapons that kill each other and the Mexicans living along the border who are trying to deal with our dung.
We are the ones who created this mess, but it's a whole lot easier to point fingers. We don't need to deal with "them," we need to fix us.
