We are in the process of securing our borders so foreigners can't sneak in. Our efforts include a huge cement wall, which is symbolic but ultimately impractical and won't work. Many feel we need to build this wall to protect us from terrorists, and of course Mexicans and Central Americans, who want all those jobs we refuse to do.

The response from Agri-business has been to close shop and move the production of food to the other side of the border, especially in receptive states like Guanaguato, in Mexico.

How secure are we when another country produces our food?
