This all sounds like a Mexican version of the old Nazi "Blood and Soil" myths, with a heavy dose of Marxism thrown in. The Nazi myths spoke of some idyllic past where people were of an ethnically "pure" race, lived a collectivist, agrarian existence, and worshipped their pagan, pre-Christian gods.
I think this appeals to racist losers of all races -- they all romanticize a past that was in fact brutal drudgery for their ancestors.
This is also a revolt against modernity. For millions of years, humans subsisted in small bands or tribes that were based on ethnic identity and kinship. They lived in what were essentially primitive collective farms (and before that, they were hunter-gatherers). People didn't vote -- everything was determined by a small class of priests and elders. Civilization, with its emphasis on money, trade, written language, contracts, and political organization not based on race or tribe changed all of that.
At the heart of all totalitarian movements is the desire to turn back 5,000 years of civilization. There are those who see themselves as a new class of priests, eager to rule over the peasants. There are also those who see themselves as peasants -- they get a false sense of security by imagining that they belong to a "tribe" or "race" that will protect them from "those people" (whoever "those people" happen to be), and they imagine that the would-be priests will take care of them rather than expliot them.
Civilization is a new invention, and in the best of circumstances it hangs on by a thin thread. The enemies of civilization are always among us -- whether they be communists, or Nazis, or Luddites, or religious fanatics.
