In one of the preceding chapters we have tried to show how the Romans in the second century before our era attempted to check the decline of morals and the growth of extravagance by giving the censor extraordinary discretionary power over the daily life of the citizens. It may be interesting in this connection to say a word of three or four other cases of paternalism, in which the state interfered in private life or business in the hope of correcting some widespread evil or social disorder. All of these social evils which Rome tried to remedy have their analogues in our own times. The most outstanding of these problems was unemployment and lack of food in the large cities. This was the problem which Gaius Gracchus tried to solve by his corn law in 123 B.C. Our best estimates put the population of Rome at 800,000 in the early Empire.[35] Perhaps it numbered a half million in the time of the Gracchi. Italy, after supplying her own needs, was unable to provide all these people with sufficient food, or with food at prices within the reach of the poor. In times of great scarcity previous governments had tried to meet the difficulty by bringing grain to Rome from Sicily and Sardinia. The motives which actuated them were not primarily humanitarian. But a hungry proletariat would have threatened the existence of society and government. Gaius Gracchus tried to do in a systematic way what some of his predecessors had attempted in an irregular fashion. He organized the purchase and transportation of grain from the provinces and provided for its sale at about half the market price. He may have thought of this measure as a temporary palliative to meet an emergency. He may have hoped later to do away with unemployment, by developing the industries of Rome and settling the needy in colonies. He may have expected to stimulate agriculture in Italy and in that way to bring down the price of food. But the immediate result was the recognition by the state of its duty to provide food for the city, and to adjust the price of the necessities of life to the purse of the consumer. Within seventy-five years after the tribunate of Gracchus we hear of four or five new corn laws, each one increasing the amount of grain supplied by the government or lowering its price. The democratic leader, Clodius, in 58 B.C. even supplied grain free to the needy. Suetonius tells us that Caesar introduced a partial reform by cutting down the number of people who received cheap or free grain from 320,000 to 150,000. This essay in the fixing of prices by the government which Gracchus made in 123 B.C. was carried to its logical conclusion by Diocletian in his famous edict in 301 A.D. In another place the present writer has made a study of this decree, which was found in Asia Minor some two centuries ago engraved on tablets.[36] It is sufficient to note here that in this document the Emperor fixed the maximum prices which it was
