Final answer:
The Inca economy was controlled by the government and was structured around egalitarian principles, with contributions stored in warehouses and the land managed collectively by community groups known as ayllu.
Step-by-step explanation:
The Inca economy was unique in that it was controlled by the government. This was a system that emphasized collectivism over individual accumulation of wealth. Each village contributed to the overall prosperity of the society, and their contributions were stored in large warehouses to support all citizens, particularly in times of need. The government's control extended to organizing labor and construction of public works through a system known as mita. Furthermore, ancient Inca society was structured around the ayllu, which was a community group that managed the land collectively and divided the crops as needed. This economic structure promoted egalitarianism, as it did not allow for significant differences in wealth among the general populace, with the exception of the ruling elite.
