Jomini, while some of your observations are correct others show a certain degree of ignorance. For military tech you mention that the Natives claimed some their victories through indirect or pitched battles, but the Spanish were notorious for the same tactics. For production tech you say that Natives could not match European agricultural productivity, but then you have to explain how corn and potatoes managed to support populations that were equally dense if not more so than most of Europe, not to mention the vast areas over which these crops were spread. For government you say that a lack of paper and math hindered them, but Mesoamericans had paper and Andean cultures recorded information via quipu and both had a complex understanding of mathematical concepts. Additionally, your claim that "the Spaniards elected to "bribe" the Mesoamericans by teaching them European agriculture and technology" is terribly incorrect. It's quite well known that the Spanish upheld most facets of Native culture. Native legal systems, agricultural techniques, property rights, military structures and so on were upheld. The Spanish primarily pacified the nobility, formed political connections with the local states, and converted the bulk of the population. Any transference of Spanish technology and agriculture would have been the unintentional result of incoming Spanish colonists, not a direct effort by the Spanish to "bribe" the locals.
