Ernesto Zedillo quotes:

I have proudly affirmed that the Mexican nation extends beyond the territory enclosed by its borders and that Mexican migrants are an important - a very important - part of this.

What we need to do first is to find out how big the migration problem is and what the economic consequences of it are for the United States and Mexico. We hear a lot of extravagant numbers and claims made, but very few hard facts. We don't really know what, if any, burdens illegal migrants impose on the US economy or the social welfare apparatus, and those issues must be clarified.

Fortunately, both governments have been in favor of studying the Mexican migration problem in greater depth. For the first time, I think, we will have something scientifically sound that says something about this phenomenon. The study is ongoing, and I hope that, with a push from both of us, it will provide a sound basis for serious public discussion on the migration issue.
