They are making Mexico a better place to live by encouraging uneducated peasants to emigrate to the United States. These people are no longer a burden on Mexico, occupying their schools, using their hospitals or their welfare services. They have transferred their problems to the United States and the illegals even wire money back to Mexico.
Imagine if we encouraged 20 million of our uneducated underperformers to relocate to Canada, use their services and send millions of dollars back to the U.S. every week to help the U.S. economy.
That is a valid point.
