And certainly in Rome. Long before their were Popes--before there were Emperors--there were those who achieved the privilege of governing--rather "looting" a province in a manner that became the stuff of legend. The practice was so endemic that it was the very absence of private greed that became the topic of note. Here's Plutarch, remarking on Caesar's Brutus:
 μέλλων δὲ διαβαίνειν εἰς Λιβύην Καῖσαρ ἐπὶ Κάτωνα καὶ ΣκηπίωναΒρούτῳ τὴν ἐντὸς Ἄλπεων Γαλατίαν ἐπέτρεψεν εὐτυχίᾳ τινὶ τῆςἐπαρχίας: τὰς γὰρ ἄλλας ὕβρει καὶ πλεονεξίᾳ τῶν πεπιστευμένων ὥσπεραἰχμαλώτους διαφορούντων, ἐκείνοις καὶ τῶν πρόσθεν ἀτυχημάτωνπαῦλα καὶ παραμυθία Βροῦτος ἦν.  καὶ τὴν χάριν εἰς Καίσαρα πάντωνἀνῆπτεν, ὡς αὐτῷ μετὰ τὴν ἐπάνοδον περιϊόντι τὴν Ἰταλίαν ἥδιστονθέαμα τὰς ὑπὸ Βρούτῳ πόλεις γενέσθαι, καὶ Βροῦτον αὐτόν, αὔξοντα τὴνἐκείνου τιμὴν καὶ συνόντα κεχαρισμένως.
 When Caesar was about to cross over into Africa against Cato and Scipio, he put Brutus in charge of Cisalpine Gaul, to the great good-fortune of the province; for while the other provinces, owing to the insolence and rapacity of their governors, were plundered as though they had been conquered in war, to the people of his province Brutus meant relief and consolation even for their former misfortunes.  And he attached the gratitude of all to Caesar, so that, after Caesar's return, and as he traversed Italy, he found the cities under Brutus a most pleasing sight, as well as Brutus himself, who enhanced his honour and was a delightful companion.Bernadotte Perrin ed. 1918, Loeb Classical Library reprinted at Perseus here and here.
