They say that the state of the Aztecs is like Assyria, and the state of the Incas is like Ancient Egypt. How is this similarity manifested?

Among the Aztecs, the military aristocracy played the main role, as in Sparta and Assyria. The Incas had a bureaucratic monarchy, as in the Kingdom of Job in Egypt or in Han China. The reason for this similarity lies, apparently, in the fact that the natural conditions of Egypt, China and Peru made it difficult to trade with the surrounding countries, but made it easier for officials to control the exchange of goods within the country.
