Until we have a legitimate labor market between Mexico and the United States, people will attempt to come here to work.

The image and the costs of a Berlin-like wall or a Great Wall of China is something that the American people have not accepted to date.

Six million jobs in the US depend on trade with Mexico. Ten border states - six in Mexico and four in the United States - combined have the third or fourth largest economy in the world. Twenty-nine US states depend on Mexico as their primary export market.

The Mexican people are increasingly middle class, and Mexico has substantially become a middle-class society. This is true despite the significant poverty, and the class and geographic inequality that have deep historical roots.

People should remember that Mexican migration is now at a net negative. More Mexicans are leaving through deportation and voluntary return than are entering the United States legally and illegally.

The cry of "Make America Great Again" reflects accurately that, after the fall of the Soviet Union, the sole superpower status of the United States is coming to an end. For the first time since the second World War, we are not the sole dominant economy in the world. In large part this is because of the success of policies followed by the United States to create an environment, a peaceful period in history in which economies could grow and countries could benefit.

People in our so-called Rust Belt have lost out, and politics and society have not been responsive either in providing the kind of additional support they need or to retrain them for jobs that are being created in the new economy.
