This begs the interesting question of just how did the Spanish regard the Natives after the Conquest. The Counsel of Viadollid held that they were not slaves, but this was largely ignored in practice as the Spanish established economedias, granting the Conquistadores land and the natives on it in order to guide them to Christianity. Unfortunately, those natives quickly became the equivalent of Medieval serfs, and, in my view, this prejudice continues to smother the Mexican economy. More important, however was the notion which persisted into the 18th Century that wealth was a fixed quantity which could not be created, but only shifted from one owner to another. The Industrial Revolution has shown us otherwise, and we see now that wealth is created by expanding an economy, increasing both demand and productivity. A slave system cannot do this, and I would assume that any highly advanced civilization would know that.
The World Economic Council, the Democrat Party in the U.S., and the Left around the world DO NOT KNOW THIS.
They seek to enslave the "non-elite" humans around the world.
Then, once enslaved, they plan to reduce our numbers dramatically so as to save the planet from our consumption of its resources.
