The vast millions of illegal aliens from Mexico in this country didn't cross the desert, they came in cars, vans, pickups, and buses through U.S. customs at the border with a visa authorizing them to enter.

They simply overstayed their visas, with the help of everyone from organized religion to organized crime and organized labor. The U.S. public school system is a huger enabler.

But the U.S. Government is the single largest illegal alien enabler, and harbors tens of millions of them through free public food, housing, healthcare, and services in every county in every state in the country.
