This basic principle of US immigration policy holds that the dirt on the north side of the Rio Grande is distinct from that on the south side and has magical qualities. This magic dirt can fundamentally change a person or even vast groups of people. However, there are tricks to this bit of special earth. It can, for example, take a Hispanic person, raised in a Spanish-speaking home to parents who fully identify culturally, ethnically and nationally as Mexican, and transform that person into one of us. Such is the impressive power of the magic dirt!
Like all magic though, this dirt is limited by special rules and tricks one must know to be able to harness its power. For example, the magic only works on Hispanic immigrants born on the north side of the Rio Grande. A child born to a Mexican mother on the north side is transformed by the magic dirt into one of us! But a child born to a Mexican mother on the south side and who immediately crosses the river is not affected by the soil. Futhermore, so powerful is the magic of the dirt that is a can impart its transforming powers to the family members – sometimes even extended family members a thousand miles away – of a child born upon it. This dirt is truly amazing!
Most governments on this planet control only ordinary, natural dirt. Therefore, they are limited to ordinary, natural immigration policies. They restrict citizenship to their own people and those few immigrants they need who can improve their society and blend into the native population. But because of the Magic Dirt Principle the United States can accept an unlimited number of millions of immigrants from anywhere on the planet, born to families of any culture and holding any allegiance. No matter their physical, cultural, religious or ideological condition – they are transformed into one of us thanks to the magic dirt!
