The third world migration is encourage to ease the cost of extraction of resources
1. After the conquest of the Americas, Spain was the richest nation on earth; hardly "third world."
2. Comparatively little resource extraction, except for oil and gas, happens in wealthy countries because those resources have already been heavily exploited, the environmental and economic costs are huge, and it is much cheaper to extract in the third world, though countries like Australia are an exception. What is more, those in rich countries doing the extraction are overwhelmingly Caucasian.
3. As for agriculture, rich countries are usually rich because they have been successful in reorienting their economies so that most of the labor force works in more profitable sectors, meaning we have to import labor to work on the farm.
4. Manufacturing and, increasingly, services, are produced much more cheaply in the third world. This is done without the need for mass migration.
eradicate Caucasian from the land
If you believe that there were Caucasians in the Americas before European settlement, perhaps you'd be interested in the Book of Mormon...
To conclude, this mass migration was first enacted by the Spanish settlers in South America or today's Argentina to eradicate the Indian tribes.
1. Argentina was settled comparatively late by Europeans in comparison to Mexico or Peru.
2. The European population of Argentina settled largely in the nineteenth century, with mass migration from Italy, Germany, Britain, Poland and Austria as well as Spain.
3. While Spanish settlement in the Americas was cruel and bloody, it did not seek to eradicate the native population. The majority of the population of Paraguay is mestizo and the most common language is Guarani, not Spanish.
We are next.
I think you've missed out a couple of mass migrations in between like, um, the Anglo migration to Canada?
