Please answer the following question: I know that the answer to the question "What would help the Ottomans reach their ultimate goal?" is in "The Ottoman economic mind was closely related to the basic concepts of state and society in the Middle East in which the ultimate goal of a state was consolidation and extension of the ruler's power, and the way to reach it was to get rich resources of revenues by making the productive classes prosperous. The ultimate aim was to increase the state revenues without damaging the prosperity of subjects to prevent the emergence of social disorder and to keep the traditional organization of the society intact.". Can you tell me what it is?
A:
get rich resources of revenues
