Worker's paradise?

Today I read an article on the Jesuit Reductions of South America, and posted it over at The New Beginning. Was the evangelization of the Guaraní halted with the destruction of these Jesuit missions? How many Guaraní today are Catholic? How much of the current state of S. American countries is due to the injustices perpetuated by those with power? How great of an impediment to evangelization has been created by these so-called "Catholics"? Did the Church fail to excommunicate when it should have, even at the risk of persecution? And what have the liberal revolutionaries done to improve the situation for the poor? (How anti-Church and anti-clerical were they?)

Should the Reductions be considered to have been truly self-sufficient polities? What sort of crops did they cultivate for food? Did they domesticate animals? What can the transition of these hunter-gatherers to agriculture teach us about limiting the ecological footprint of our communities? While their adoption of European culture (especially music) as their own is well-known, is this an example of cultural imperialism? Or is it the case that the Guaraní found European music to be truly beautiful?

The Reductions were an example of communes--property was owned in common, I believe--though it is not clear to me if there was no private property whatsoever. Were they Communist? Not at all--they were Christian in inspiration. I do not know if the Guaraní owned things in common as hunter-gatherers, and if this was something they carried over into the Reductions, or if it was introduced by the Jesuits. Who exercised leadership in the Reductions? The Jesuits? The Guaraní? A select group among the Guaraní? The Jesuits and the Guaraní jointly? I should see if there are any good histories that would provide the answers to these sorts of questions.

Was this sad event an example of just polities being destroyed by empire? The oppression of the peaceful and relatively powerless by the powerful and the rich?

Tonight I checked out Fr. Augustine Thompson's Cities of God from O'Neill. I will be looking to the Italian city-states to see what sort of lessons can be drawn for the science of politics. Does the conversion of peoples lead to the formation of healthier political communities? And if so, why did it not happen, especially with the Germanic tribes? How does one account for the rise of monarchies and the feudal system? Would not tribes be more likely to have some sort of democratic government? Or did the Germanic tribes grow too big in size for this to be practically possible? Was the feudal system rooted in the customs proper to tribal alliances/subordination?
When did the Germanic tribes start practicing agriculture? Were there different social strata/classes within the tribes?

So many questions for me to find answers to...
