Aztec Job Specialization

Since the Aztec population had increased so greatly from the start of them farming, not all Aztec had to farm. These other Aztec would do stuff like weave clothes, sweep the streets, be medics and doctors, be teachers, be priests, cook the meals, sell food and clothes at the market, be stone carvers and make tools and weapons. These specialized jobs led to the Aztecs advanced technologies. One advanced technology of the Aztec was obsidian weapons. These weapons would never have been as good as they were if the Aztec hadn't had specialized jobs. Maybe, if the Aztec hadn't had specialized jobs, they wouldn't have had such good weapons so they wouldn't have conquered so many other civilizations. This would have made it so when the Spanish showed up, the Aztec wouldn't have had very many enemies so the Spanish wouldn't have grown such a big army making it so the Aztec could have beaten the Spanish. Who knows, maybe if that had happened, the Aztec would be the main civilization in the Americas.
