Hanson: I think there's three or four that could be done that would actually change the dynamic and bring us back to a situation that we had in the past.

One, of course, as Michael said, is to enforce employer sanctions.

Second, we have to change the calculus in the United States that sends the message to Mexicans in Mexico that if you come across as a worker you're going to be expected to learn English, you're going to be expected to put your kids in a school where they're going to have immersion into the English language and you're not going to be able to reduplicate the culture of Mexico.

And then the third, I think besides employer sanctions and changing our attitude that transmits to the border, very important to work on economic development with Mexico.
