From Cassius Dio's proposals spoken by the mouth of Maecenas in Book 52 of his Roman History we can comprehend what intention senators had early in the 3rd century. In chapters 28-29, Dio insisted that all property which produced any profit for its possessors should be taxed. He proposed the tax-system founded on the doctrine of Callistratus that praediorum collationes non personae sed locorum munera sunt. By this tax-system he intended to release the well-to-do from being subjected to the abuses of the cities. The cities compelled the well-to-do, in view of their personae, to contribute more than the value of their possessions demanded. According to the doctrine of Callistratus even those who had obtained exemption from the munus publicum couldn't avoid any praediorum collationes. Nevertheless they preferred to relinquish exemption from the collationes extraordinariae rather than be subjected to the abuses. Dio intended to spare the well-to-do the burden by denying the allotment the cities conducted. In chapter 30 also, Dio intended to reduce the burden the cities compelled the well-to-do to bear. And he insisted that the cities should abandon their nominal autonomy in order to cut down the expenditure of the cities. Therefore the proposal in 30. 9 that the cities of the Empire should not be allowed to have individual coinages is clearly to be regarded as a belief that city coinages should be banned, not as a belief that monetary systems incompatible with the Roman monetary system should be banned. By this proposal Dio intended to release the cities, eventually the well-to-do, from the burden which city coinages caused. Dio's economic proposals as well as his political proposals looked after the interests of the well-to-do, not of the Empire. The burden which the cities compelled the well-to-do to bear was increasingly heavy. To reduce the expenditure of the cities by abandoning the titular autonomy was beneficial to the well-to-do who strove to cut down their expenditure.
