There is a story in ancient Rome of Cincinnatus- the hero who took political power at the specific request of the Senate and then saved the city when it was menaced by the Volscians and the Aequi. The same thing happened again when the city was faced with a revolt by the plebians- the same class as Cincinnatus himself.
In each case, when his job was done, he relinquished power and returned to his farm where he lived modestly.
I don't think he filled his boots with consultancy jobs which he was not really qualified for and which were offered to him entirely because he had previously held supreme power. He therefore did not aim to make as much money as possible by exploiting his previous status.
No- that epitome of greed is one Tony Blair.
