There is a funny story about the real currency of power that involves Stalin. The story goes that Stalin and his party officials came upon a beggerwoman on the side of the road. She asked them if they could spare some money. In a rare moment of generosity from Stalin he went for his wallet, only to find it empty. He asked the officials if they had any money, but all of their purses sounded empty.

Those in power do not need money, as everything they ever want will be given to them.
